  • The Functional Shred is an amazing program that is equal parts fun and challenging. It will definitely take your fitness to the next level no matter where you're starting from ... I really appreciated Jay's thoughtful warmup and cool down sequences that bookend the workouts with intention and mindful movements to promote longevity for athletes like myself who push the limits of what their body can handle. Thanks for kicking my butt Jay! Can't wait to start the next program!

  • This is by far the most fun program I've ever done! I had just finished a bulk before starting The Functional Shred and I was struggling to lose the last few pounds. The Functional Shred was not only fun to do but I've gained strength, improved mobility, and gained core strength! I had a C section 4 years ago and my abs have been the most difficult thing for me to improve due to the lack of strength after the surgery...my abs are stronger now and I FINALLY have a 6 pack! Very happy with my results!

  • 10 months ago I started training with Jay's programs. I have followed The Functional Mass and Power program twice. Besides that I have been following The Bodyweight Beast program as well. This is my 1 year progress/transformation. Jay's programs combined with a diet (6 days a week) and not drinking alcohol anymore has truly been a life changer for me. I haven't felt this good in a long time both mentally and physically.

  • Hi, JT! Just wanted to say THANK YOU. I'm almost done with Functional Mass and Power and I couldn't be happier with the results! I thought it would only help me recover after the lockdown muscle loss, but I had no idea it would get me in the best shape ever! Question now is...which program should I do next?!

  • Wanted to share my 1 year progression with TFS and some of your bodyweight workout from you instagram. So, from 103 kg to 88 kg with great training and discipline regarding food I managed to improve my overall resistance, body strength, and of course the physical appearance changed also. Just grabbed two of your bodyweight programs and can’t wait to try them! Love what you’re doing. You’re a great inspiration, please never stop, you are great!

  • Hi Jay, Had a moment of self appreciation and wanted to share with you. August 2020 had foot surgery (right) then November 2020 (left)…. Had a set back and gained some weight…20lbs to be exact. Since January 2021 , I have been doing your programs, functional Shred (twice), functional mass and power, functional method 2, and functional method 3 (currently on).…….also have lost all the extra weight i had gained last year. Did not realize i made this much progress visually too. Just wanted to share.

  • In the beginning of the year I got COVID.I couldn't workout for a few weeks and got into some bad eating habits. I needed a reset, so I got the JTMFIT Kettlebell Shred. I have loved the program!, I have leaned out, increased muscle endurance, improved my kettlebell technique, and I have a stronger core. Thanks for another great program, Jay!


I’m Jay and this is my story

I’m a recovering alcoholic/addict and type 1 diabetic who has faced their share of adversity in life. When I got sober back in 2005, fitness was one of the things that took my life in a positive direction. I found motivation and purpose through challenging myself day in and day out.

I was a personal trainer for over 12 years helping hundreds of people make profound changes in their lives. I eventually founded JTM FIT INC and created online training programs that have helped thousands and thousands of people all over the world make incredible physical and mental transformations.

My mission is to share what I have learned in order to inspire you to rise above your challenges, to rise above your perceived limits, and to rise above anything that’s stopping you from becoming the best possible version of yourself.
