Re: Is this the Marcus that taught the cardio-hype classes on Fort Meade (EAGLE gym) in the early 00s ??
I was in the Army back then and I remember somebody named Marcus coming through - this is in the summer 2001 to late 2002 era for me.  All I know is one day I looked in the gymnasium window and saw you leading a Cardio Kickboxing class for the military wives and you did a 360 aerial-roundhouse kick and landed in a split and without hesitation, you shot back up like a NASA rocket.  But, what I had seen you do reminded me that there are deeper layers to life and self-control through the spirit. I never forgot your presence.
Good to see you are still vibrant and motivated - those of us that interacted with you in the Meade-era had nothing but utmost respect.  Never underestimate the lasting-impact you have had on people that you randomly cross paths with. Thanks again Marcus DeValentino.  Wish you the Greatest !!! . . .  PEACE.

"Mr. DeValentino and I were in the martial arts/fitness industry promoting a program known as Cardio Kickboxing®. We didn't see each other in person that often but communicated primarily through e-mail and by phone occasionally. He took over the reins of managing the program and took it to a higher and professional level. We are like-minded politically, spiritually, economically and I respect him and his integrity more than anyone I know."

Hi Marcus,
I really enjoyed your Cardio Kickboxing® Instructor workshop at the Gold' Gym of Crofton, Maryland on August 7, 2011 and would definitely recommend to others.  I am very excited to start classes, as I have gotten a big response already.  Thanks for your help and it was a pleasure to work with you.

Good Morning Marcus DeValentino,

With teaching my own classes, I had almost forgotten how much I enjoyed your Cardio Kickboxing® workouts! Your   enthusiasm and love for what you do is so contagious and inspiring. It has been a timely revisit to your class for me though; it has amped me up and gotten me excited to carry "our" beloved Cardio Kickboxing® program to Panama City as I relocate from Hawaii. Thanks for all you do!

Have a blessed day! ------------- Cheri

I received it (Your website Cardio Kickboxing® Music Mix CDs and Workout DVDs package) today.  Thank you so much.  Please keep me posted of your sale.  SO far, I like the music.  It's great.  I'm sure the DVD will be good too.  I am a Personal Trainer and Group Exercise Instructor and have been teaching for almost 10 years now.  I came across your website by accident and watched the clip and I liked it.  I was just going to buy 1 tape and really glad that I bought the package.  I have been listening to your music and it's awesome.  This will blow my students away!   Also the choreography are so simple.  Can't wait to finish watching all DVD volumes.  I will definitely share the other instructors your site.

Dear Marcus DeValentino,

I think this past September 5, 2010 workshop at Hickam AFB Fitness was the best one so far.  You really focused on technique and I really needed that.  We ALL needed that.  I hope you will consider holding instructor workshops for those of us who are unable to attend your workouts on a regular basis so that we don't develop bad habits.  I loved your Tri-pump strength training technique and some of the new stretches....FANTASTIC workshop! 

Thank you!

Marcus DeValentino,

It was such a pleasure to be able to drive down from Georgia to North Carolina and have the privilege to workout and re certify with you again!  What a wonderful group of people at as well!  I am glad to know that you and Wanda are back home safely in Hawaii.   I am already ready for next year! :)

Thanks so much again for the privilege to recert with you in person!  I had a great time meeting all of the ladies and Scott at Maximum as well!  They were such a wonderful group of Cardio Kickboxing Instructors!  Hope you have a blessed week.  Keep in touch.

Marcus DeValentino, Cardio Kickboxing CEO:

I wanted to take a moment to mention my results from your Cardio Kickboxing® workouts over the past few months.  Back in late January, I volunteered for the 2010 Winter Olympics in Vancouver, BC, Canada, and had the time of my life.  Actually...I had way too much fun!  I came back the heaviest I've ever been in my life and feeling just as poor at 254 lbs, 25% Body Fat and my Physical Readiness Test was due in 10 weeks.

I began loyal attendance at your Saturday morning and Monday evening classes and eventually joined the Tuesday and Thursday evening classes with Mike Pajil at Hickam AFB Fitness.  Between taking the extra classes, changing my diet to include no more soda and a ton more veggies, I noticed a slight change in my energy levels.  By the time the PRT came around last week, I was thrilled to see the current results.  I came down to 240 lbs, 22% Body Fat and best of all made an Excellent - Low on my PRT!!   I really look forward to continuing with the classes.  It works for me, and I'm certain that these classes will work for many others too!!

Take Care, Blue Skies and Be Safe!!!

Hello Marcus DeValentino,

I just want to say thank you for all your help in my quest to get in shape.  Your classes are wonderful and as you can see I have lost lots of weight and inches because of them.  I feel so energized and I can't wait to take it to the next level!  By the way my first 5 weeks taking cardio kickboxing I lost 13 pounds and 4 inches in my waist.  So, I am living proof that this is the ultimate workout.  Thanks again for all your help and advice.  Love the website!

Kyoshi DeValentino!

We held our 1st Cardio Kickboxing classes in Beulaville last night!  What an experience!  We have had a tremendous response - almost 60 clients!  Both classes went very well.  It is exciting to know that we will be helping and encouraging others to become more fit!  We all have been very blessed by this entire undertaking.

Thank you so much for all that you have done for us!  We will keep you posted on our progress!

God Bless,

Hey Marcus,

I wanted to thank you.  You brought my fitness to a whole new level and fired up my body again.  I have been runner for a long time but I had plateaued and was not losing any more un-wanted weight until I showed up to your Saturday class in Pearl Harbor in March 09.  Since then I have lost some significant weight.  Your program will also help me with the Warrant Officer Candidate course.  Once again thank you and I wish you and all the cardio kickboxing Saturday crew good luck.

Hi Marcus,

I just wanted to update you on how I did this weekend with the classes.  I had an awesome time!!  When I got over the initial nervousness I think I did a GREAT job!!:)  I really was able to let go and get into the class and I had nothing but great reviews today from the students.  They were all asking when I was coming back and why I wasn't teaching permanently :)  That really made me feel so good.

I look forward to growing more in the future with your Cardio Kickboxing Training & certification.  Thank you so much for your push :)   Also one of the students was asking me how to get certified and how I got into teaching and so I headed her in your direction!  I gave her the web site and let her know you were the go to guy. 

Well do take care this week and God Bless,

Hi My Friend,

Thank you SOOOOO much for the fantastic Cardio Kickboxing DVD vol. 3 "More Power".  I just watched it and it was just like we did during your annual visit up to Pellitier's Karate Academy here in Lewiston, ME.  It sure brings back good memories.  You could not have picked a more perfect one to send me. You are the best friend I could ask for.  Hope everything is fine with you way out there in Hawaii.

Believe it or not, I have been engaging affirmations and visualizations about being back...I play your workout videotapes every morning as my daily motivational inspiration.  I am so happy that I have them.  Now, it will become a reality, AGAIN! IMUA!

Thank you so much for all of your hard work and dedication to the Martial Arts and especially to the official Cardio Kickboxing program.  I have loved this form of exercise for a very long time and working with you has given me a deeper understanding of the program and it's benefits.  Your exceptional knowledge and grasp of technique and execution is unrivaled in Mixed Martial Arts Coaching Science.  Thank you again for your Pearl Harbor Hawaii workshop on May 18, 2008 and certification.

Master Marcus,

Thanks for the analysis on Natural Speed e.g. Bruce Lee vs. Mechanical speed e.g. Chuck Norris.  Always enlightening... (and you said there was nothing more for you to teach me - LOL).

I always learn something new every time we get to train together, and I just love that!  That big grin I get when it's fast and furious during the workouts is a by-product of our spirits and energies movin' to the groovin'!  And I'm always ready to volunteer or let you demonstrate a technique on me for the benefit of the class.  Thank you sir!  May I have another?!  LOL

Thanks again Marcus, you are a blessing to all of us.

How are you doing Sir?  I miss your class very much.  I got out of the Navy in Mar of 2007.  I was apart of your afternoon Fitness Enhancement Program class in 2006 on Pearl Harbor.
At the time of my separation I weighed 287 lbs following my knee surgery.  I have since used the skills you taught, from warm-up to finish.  I am proud to say I am now 190 lbs with 19% body fat.  Thank you very much for your time and your knowledge.  I hope all is well with you.

Take care

I just got my DVD’s today.  Haven’t had a chance to exercise to them yet, but I did put each one in and watch a little of each DVD.  The choreography and combinations are just what I was looking for.  I’ve gone to kickboxing classes at the gym and the instructors were so spastic and tempo so fast it was impossible to follow much less correctly execute the moves.  Recently, I purchased a freestanding bag and I can’t wait to try new stuff.  I was glad to see that you moved to a smaller studio when filming because you can hear your instructions and music better.  I look forward to getting your Cardio Kickboxing music CDs in the mail tomorrow.
Thanks again.

Hi Marcus, 

I am very pleased that it was so easy to find you on the internet.  Great website!  I was in your Cardio Kickboxing class on Pearl Harbor in 2000 – 2002.  I loved it so much and have been unable to find anything similar or so much fun since moving to Colorado Springs.

It’s wonderful that you and Wanda are back in Hawaii leading the cardio parties – no one motivates a class quite like you!

All my best,

Marcus san,

Domo arigato gozaimashita Sensei!  Had an awesome experience training with the CK team!  Look forward to lighting fires and fanning flames in New Mexico.  You are an excellent mentor and human being, and your teachers could not be more proud of you.  Thank you for your time and valuable insights.  I've not met a more talented and knowledgeable Fitness Kick Boxing instructor.  Hope I can do you proud!  Wish I had more time to stay in Hawaii and am feeling the melancholy as I depart back to the mainland today, but Hawaii keeps calling me back!  Looking forward to our next encounter, sir!

Oorah! Bring it on and Fire it up!!!  Give the girls all my best.  Couldn't have found better training partners!

I truly appreciate your taking the time, at the end of an exhausting week, to give me that additional motivation and advice.
I want to tell you how much I have enjoyed being in your classes, Marcus.  Being in the environment you create, with music and with your own spirit, reminds me of how much joy there is in moving and challenging the body and striving to reach its potential – whatever stage of life that body is in.  I fully intend to stay active as long as I can, because so many benefits flow from an active life.
Thank you for sharing your spirit, as well as your knowledge, with all of us at Bloch Arena Fitness of Pearl Harbor, Hawaii.  I wish you the absolute best as you continue with your career path.
I’ll see you in class

Thank you for a superb class/certification today. 

I've had a chance to look at the manual and am very impressed with everything in it from printable "station" cards, to choreography, to muscle group pictures, and even music websites.  I didn't get this much information from my other certifications.

Thanks again for another successful, fantastic workshop.  I had a lot of fun.  I think this is the biggest one I have been too.  I will introduce your new combo to class tonight.  I am going to try the circuit too for a Sat. class.  I have to work on it.  I am going to blast your new CD and listen while I work.

May I say to you and family, have a merry xmas and happy healthy new year.

And just to let you know out of the 70 something kickboxing tapes I enjoy yours the best, as a matter of fact yours is the only ones I have been doing and thank you for making my workouts enjoyable, and keep up the good work, and always a pleasure talking with you or I might say typing LOL.  I wish you luck of your next video.

Enjoy your holidays, and Thanks again


December 24, 2005

Dear Marcus,

You asked how I came to your web site.   I was looking for a cardio web site and yours came up and I must say I'm glad I found it.  I did receive your tape Wednesday, very quick I might add. The workout was excellent, I'm 53 years old. 
I was a runner for 10 years and had to quit around 8 years ago.  I took up Tae Bo and found it was better than running.  From 8 years until now I would say I must have bought at least close to 200 boxing and kickboxing tapes, not to mention what I gave away, sold, or got bored with.  
I am always looking for new fitness kickboxing tapes through Amazon, Ciavideo, Collega, Cathe Fredrich, etc. so when I get them I look up the instructors web site and buy more.   I get bored easily so I do between 1 - 2 hrs per day, 7 days a week. 
When I worked out with your tape this A.M.,  it felt like I  was in the class.  You kinda remind me of Billy Blanks 8 years ago, with his class sweating, now his tapes are just for money.  I still buy them but I could kick my self for doing it, cause they all repeat themselves, and he still makes up as he goes along.
How come you didn't put your tapes on infomercial like Billy?  I guarantee you, you will see, I am definitely going to buy more of your videos.   I got the More Power vol. 3 now.  I want hard, sweat and one hour or more in a workout.  Are you going to make more in the future?  

Thanks a lot

Dear Mr. DeValentino,

Thank you very much for the video.  I was searching for cardio kickboxing DVDs on the Internet and your website seemed to have most of what I was looking for.
I'm in the Navy and started cardio kickboxing when I was deployed on the USS Abraham Lincoln.  I did it for 3 months or so and I got into great shape, not to mention losing 15 pounds.
I just received the DVD's also and had to try one.  I didn't  think I should start with Volume 5 so I did the other one and its wonderful!  Exactly what I was looking for! I had so much fun and I got such a great workout.  I'm going to recommend it to all of my friends, I know they'll love it as well.
Anyway good luck on returning home to Hawaii.  Again, thank you SO much.

Mr. DeValentino,

Sorry to hear you are leaving the states to go back home.  After completing studies I plan to open a martial arts school and add a cardio kickboxing program.  I think a good cardio kickboxing class is very exciting.  I think you are an outstanding person and it will be a great loss to the Northeast area when you go back home to Hawaii. 
It has been an honor getting to know you, and I'm sure we'll meet again.

Good luck and thank you for everything!

With the Faith,

To whom this may concern
Dear Sir or Madam

This letter will serve as a recommendation for one of our faculty members.  Marcus DeValentino, whom I have had the pleasure of working with since 1999.
Another colleague, Frank Thiboutot, the founder of Cardio Kickboxing, introduced Marcus to me in 1999.  At the time that I was introduced to Marcus we were expanding operations and adding Cardio Kickboxing as a certification program to the AFPA curriculum internationally.  We felt, as did Frank Thiboutot that Marcus DeValentino would be an excellent addition to our staff.
Please refer to letter of appointment for Marcus DeValentino as further indication of our thoughts on his abilities and experience.  I have had the opportunity to review approximately 15 hours of instructional video tapes that Marcus has produced.
His work is prominently displayed on our website ( and at
Please feel free to contact me with any additional questions that you have.  I highly recommend the work of Marcus DeValentino, as I truly believe that he will be an asset to any organization.

You are an AWESOME instructor!

Hey Marcus,

Wanted to let you know that we enjoyed the seminar.  Today was our first Cardio Kickboxing Class and it went great. The people really loved it and I think it's going to be a big "hit".  We already have sign-ups for the class into the middle of next month and that's just after one class.  Keep me on your mailing list and let me know if you have any other seminars coming up.

Thank you very much.

Hello My Dearest Friend,

Marcus, I am totally amazed at your website!  It has been a long time since I have visited.  I am on Spring break now and I wanted to come back and check things out.  It has been almost 5 years since I met you on that fateful day at Hickam AFB when you were teaching your CK classes in Honolulu.  I first attended because I had let myself get out of shape and a friend had heard about you and she wanted us to both go and take your class.  I was totally blown away from that very first class and then I was absolutely hooked!  And here I am, a CK instructor myself teaching YOUR classes at Pearl Harbor Fitness and now also at Nuuanu YMCA on top of working full time as a microbiologist and going to school part time for my second degree.  I wouldn’t be able to accomplish all that I have so far if it wasn’t for you and CK.

You have basically changed my life around.  I needed to lose weight first of all and I was able to do that.  Since I have started with you I have lost a total of close to 30lbs.  I used to wear a size 10 and now I am a size 4 and have been able to maintain that for 2 years now.  My energy level is over the top too.  You not only made me healthier but also gave me a lot of self confidence to believe in myself and to accomplish anything I set my mind to.  I had a lot of self doubt but now I don’t anymore.  When I was with you I saw how many people you helped and inspired and it made me want to do the same thing too.  I was very reluctant at first but you gave me the courage to teach CK and also get back into my love of martial arts again after all these years.

I now also sub martial art classes at the Y and have taught a women’s self-defense workshop at Pearl Harbor Fitness.  On top of everything else I also practice Tang Soo Do with your very good friend and fellow martial artist Ron Pohnel.  I am also a member of his Honolulu Sparring Club.  I also practice a variety of other styles including Kajukenbo with one of your former instructors Grand Master Ed Lewis at the Leeward Kenpo School when I can.

I have gotten my son into martial arts too and is also a member of the Sparring Club and he has started competing. When you were here last year for your workshop and the World Black Belt tournament at which you were honored, my son won his first competition and you presented him with your bo that you demonstrated with.  He was speechless when you gave it to him.  He treasures it.  Thank you Marcus.  I am now teaching 4 classes a week and class numbers are growing.

I have become a bag addict and love teaching techniques on that Wavemaster heavy bag.  Two of my student kickboxing girls started with me and were able to meet you.  Jan Coombs also decided to get certified after only 2 weeks of being in my class.  Now she teaches Cardio Kickboxing at Waianae High School where she is a P.E. teacher.  She is also a member of our Sparring Club along with Tyra.

Both now practice Tang Soo Do and Kajukenbo and spar with me.  Tyra and Jan both fight competively now and they both placed 1st and 2nd in a regional tournament last month and they went on to the Nationals in Utah to compete last Saturday.  Tyra called me to tell me that she placed 1st and Jan placed 2nd overall in the women’s colored belt division. Honolulu Sparring Club fought as a team and placed 2nd overall.  We put Hawaii on the map! I am so proud of my kickboxing girls.

When you left Hawaii you had told me that an instructor’s greatest achievement is when your student becomes even better or grows to greater heights than you and now I think I know what you mean.  They tell me how much I have inspired them and guess what, that’s how it started with you! Although you are many miles away now but you always inspire me and continue to amaze me.  I owe it to you for how far I have come and for allowing me to pass on your legacy.  You are by far the best of the BEST!!  Thank you for being my friend, my inspiration and my Sensei.

Love and Aloha always,

Mineyo Shimojo

Good morning Marcus, I went to my first kickboxing cardio class here in San Diego last night at LA Fitness Club. You know what the instructor told me?  Good Form.  Can you believe it?  It's been five years since I've been your student.  Me!  The new girl in her class with oh 25 other girls and she walked over by me and said good form.  It's all because of my wonderful master (you).  My body didn't forget.  I will always have love and admiration in my heart for you Marcus.

Have a blessed day,

Aloha & Mahalo Bettina.

Do you want to hear a success story?  In the last 12 months I've lost 14 lbs, reduced body fat % from 35 to 27, lowered my cholesterol and blood pressure, and have more flexibility than ever.  This is due to YOUR CK CLASS and a change in my diet. I have been doing aerobics/step classes for almost 20 yrs and never gotten these dramatic results.  I feel great and I'm glad that even as I push 50 I still have a lot of control over my health and well being.  So THANK YOU VERY MUCH! Hooray for kickboxing!


Until Wednesday,




Hi Marcus,

Its been 3 weeks now since I started going to your cardio kickboxing.  I could not believe how motivated I am.  Your music, your style is awesome.  I'm beginning to see a new and improve me.  I can't wait to take your martial arts class...your kickboxing class is so addicting that I sometimes go twice a day!!!  Looking forward to hear you say "Go Chris" in your class.

Thanks for being a friend

Hi Marcus!

Just wanted to check out your page, pretty cool!  Your cardio kickboxing class has really stepped up my cardiovascular fitness training and helped me to lose a lot of weight!  I love it!  The best part of the class for me, aside from the awesome instructor, of course, is hitting the bag!  I have developed so much more confidence in myself since I began taking your class.  I may even be ready to take a Karate class with you!  Thanks for everything Marcus!  You are a truly wonderful person and I am grateful to had the opportunity to learn from you.

Angela Verna

While serving in USAF on Hickam, I 'discovered' your class.  I went as a dare with a girlfriend of mine.  We loved it; and made a point to go every class.  We both lost a lot of weight rather quickly.  After leaving the AF, I have looked for ANYTHING equivalent to your program.  NOTHING compares.  It was just recently that I decided to surf to see if you had a website by chance, and am SO glad I did.  I'm getting married in June and would like to lose about 20 pounds before the wedding but ultimate would like to lose 35-40.  I know I can do it with your tapes!!!

Thanks Marcus!

Amberly Anderson


Here's another story for all to read. 

I first heard of Marcus and his CK workout through a friend.  I finally got it in gear and attended one awhile after my friend and I spoke.  I was immediately pulled in by the music, his charisma, the energy of the class, and my energy!  I knew I had stumbled onto something that had to become a part of my life.  I had taken other CK classes before but this was the clincher.  I remember saying those magic words to him without even thinking twice..."tell me about certification".  It's been a nonstop ride ever since and not only am I now a certified CK instructor but I am also working on another certification so I can increase my options to teach CK in more places!  I now have had the opportunity to teach at several different locations but always love to come back to home base for the DeValentino workout.  I know where ever I go CK will always be a part of my life.  It is a workout that empowers not only the body, but the mind and spirit.  This transfers over to every other part of my daily life.  I also love the reaction I get when I tell people I teach cool!!!!  I know you've heard this from me before Marcus but thank you for bringing CK to me and your awesome continued support.  You have a true gift. 

Here's to you Sensei!


Thank you for all the motivation you have been providing in class.  I am not a fan of exercise and sweat.  But I find myself liking and looking forward to your cardio-kickboxing classes.  I am doubly motivated by the eight pound loss in my first two weeks!!!  Thought I would forward this cartoon because I thought of you when I received it.  (Sorry, cartoon not included.)  Thanks again--

Much aloha,

Melissa Brus


Hi Marcus,

I really appreciate your help.  My husband is very excited about my decision to become a Nationally Certified Cardio Kickboxing instructor and he is very supportive.  It really feels great to invest in myself with an opportunity I never thought possible.  I used to hate sweating and worse, exercising. I never worked out aerobically until only two years ago.  Step class got me started and although I enjoyed the classes, but still considered it more of a chore I must do.  I tried several aerobic kickboxing classes, but every one seemed to hurt my knee or was just too hard until I met you.  It gave me a totally new aspect to exercising, something I finally look forward to everyday and just can't get enough.  I really thank you for opening a door to a new life for me.  I owe every pound I lose and every cut in my muscles to your CK parties.



Marcus you are the coolest guy I've ever met.  You really know your kickboxing and as I am checking out your site I see that you teach a whole bunch of stuff... no wonder you got a spider (car)!! well anyways I've lost like 5 lbs but I've toned my muscles a lot.  I've always wanted a 6-pak and I'm starting to see 1 in your classes u make it so fun I'm gonna miss ya when ya go to MD but I'm sure that the people you have trained will do pretty good and I'm sure that ill be a pretty good teen instructor or at least I hope!!  I'll try and for anybody looking at this I know you can totally agree and if you are in MD any body and you want to have a blast and look great doing it look up where one of his classes is and GO TO IT!!





Dear Sensei,

I have received the cassette and the CDs yesterday, I want to thank you for some awesome stuff!  This is great, I watched the tape and it was very enjoyable, I will use some of the techniques for my students, once I have them down pat, again thank you! Let me know when your new dojo is set!!

Good Luck!-

I discovered kickboxing at Hickam Air Force Base in Honolulu and was amazed and motivated by Marcus.  I ended up getting several women in the neighborhood involved.  Marcus can motivate and help anybody at any fitness level enjoy and get results from kickboxing.  I am now in the Ft. Meade area and was pleasantly surprised to find out that he offers classes in this area as well.  I highly recommend his class as well as any of the numerous instructors he has personally trained!

I attended the 'Fire It Up' Cardio Kickboxing workouts on Schofield Barracks Family Fitness Center back in 1999. The class was so beneficial, I can recall that after about 4-6 weeks of your class I scored my highest score on the Army Physical Fitness Test. So I know personally the class works. My wife and I are interested in the workout tapes for CK.

I really want to thank you for the workouts I had in Hawaii, you were truly inspirational and motivating.  It wasn't that I was out of shape it was that you motivated me to go above and beyond what I was already doing in the Army.  Your program is truly a system designed to get maximum benefit at a great price.  If your travels ever take you to Sioux City, Iowa area for a program please let me know and I'll be more than happy to attend.

Thanks again and "Fire It Up!"

This is from my first aerobic instructor who used to be the athletic director at Chaminade University in the early 80's (right after I grad from college).  He has his Master's in Sports Science.  He went back to school to get his Master's in counseling and is now a counselor at one of the high schools in Las Vegas.  Again, Thank you Marcus.  It is because of you that I have been able to achieve this.  You are the BEST!.

I want to thank you again for being as good as you are at what you now do.  You have not only learned your craft well, but have learned to teach it well also.  You actually do look really great.  Your motivation seems high, and I know you will continue your fitness efforts.  Not only that, but, whenever I need a little fitness inspiration, I'll be thinking of you.




OOH RAH!!!  Your class was extremely motivating.  I really enjoyed the high energy workout.  Your method of teaching is awesome.  I plan on attending some of the other instructor's workouts. I can't wait to start teaching students of my own.

Thanks again

Well I have to admit that you are BAD-ASS Marcus.  I've been working out for some time now and I have never seen the motivation, dedication, and determination that you inspire.  It's a pure rush and a complete pleasure training out with you my friend.  I've seen hundreds of gimmicks and products but nothing comes close to what you teach.  I've seen and even tried the Billy Blank's Tae Bo workout and it's nothing compared to your Cardio Kickboxing.  I would like to be in your next instructor certification training program so that I may teach at my next assignment in California.

We would like to thank you for the improvement in the quality of our lives which has been gained through Carey's participation in your Cardio Kickboxing program.  Carey has commented many times on how much she enjoys your exercise classes and also that she feels more vibrant and energetic since she began.  Myself, I have enjoyed more physical activities w/Carey and have no longer worried about her health because prior to her starting Cardio Kickboxing, she was at a high risk for contracting diabetes due to our family history and lack of exercise.  Your zealous endeavors are a credit to yourself and, I am sure have had a positive influence on all whom you come in contact with through your program.

Hello Marcus! Good to hear from you and really miss your classes.  Believe it or not the company that took over the classes at Eagle Fitness Center recruited me to teach.  I have been teaching the lunchtime class now since December.  It has been great! I really love it.  I am actually about 10 weeks pregnant now but am still going to keep teaching until I just get too big.  My doctor said it is good for me.

Take care!

Dear Marcus

Just a short note to thank you for your time and kindness extended to me today at your Cardio Kickboxing Instructor Program in the State of Maryland USA.  Although I am looking forward to my holiday in Hawaii and to meet with your Team Cardio Kickboxing instructors there, I want to go straight home and start working and practicing.  I know I have a lot of work to do as the first to present the Original Cardio Kickboxing Program to this region of the world.

Today (January 2, 2005) it was great to train with the best of the best!  I promise to come back later in the year, and have another session with you, and knock you off your feet! (Not literally, of course!)

May I take this opportunity to wish you health, wealth and happiness in 2005, and thank you once again.

Take care,

Aloha Marcus,

I thank you for taking the time from your busy schedule to email me.  I really miss our classes in Hawaii.  I was in the class for a year and a half.  I loved it and all of my friends that joined loved it too.  We really appreciate what you and your team do for our troops, keeping us in shape and all.  I am going to order some videos because I can do my workout at home.  I am stationed in San Diego now and will be there until Jul '06.  Like I said in the guest book, I am in Iraq, but should be leaving soon.  I do miss you all so much.  You take care and keep all that energy going.
