Meet Your Coach

Your Best Years Are Still Ahead.

20+ years sober. Type 1 diabetic. Personal trainer and coach since 2008.

I spent the first 20 years of my life getting in a lot of trouble, doing a lot of drugs and getting blackout drunk. I was far from being fit and healthy.

I got sober in November of 2005 and started working out. I was 145 pounds with no muscle and no idea what I was doing. I tried a lot of different things, from Muay Thai kickboxing and BJJ to CrossFit and endurance events. Many years of hard training beat my body into the ground.

Injuries and burnout forced me to rebuild. That experience shaped The Functional Method: a way to train hard, stay athletic, and keep moving well for years to come.

Everything I learned the hard way is built into your program, so you don't have to learn it the hard way too.

Wherever you're starting from, your best years are still ahead with the right approach!

FAQ

Still Have Questions?

How is this different from other fitness apps?

Most apps give you a library of workouts and leave you to figure out the rest. JTM FIT is a complete system: structured programs, a clear progression path, brand new programming every week, plus nutrition, mindset, and mobility, all built around one method. Every program is written by Jay, so you always know exactly what to do and why.

I've been training for years. Is this too basic for me?

Definitely not. The Functional Method is built for people who already know how to train but have hit a wall. Programs like Performance, Mass & Power, and Push Pull Legs will challenge experienced lifters. The programs assume a baseline of experience, so this isn't total-beginner content.

Is this for women too?

Absolutely. Many JTM FIT members are women, and every program works the same way for you: you choose your weights and progress at your own pace. Heidi and Jessica, two of the results above, both ran Dumbbell Shred.

Which program should I start with?

It depends on where you are right now. Already training consistently? Pick the program that fits your goals and your equipment. Coming back from time off or an injury? Start with Rebuild or Full Body. Newer to training? Start with the Movement Mastery Course, 8 short lessons on the movement patterns every program is built on. Still not sure? Message Jay in the app and he'll point you in the right direction.

Do I need a gym or can I train at home?

Both work. Some programs are built for a gym or a well-equipped home gym with barbells, kettlebells, and dumbbells. Others, like Kettlebell Shred, Dumbbell Shred, and Bodyweight Burn, need minimal equipment or none at all. Whatever your setup, there's a program in the app built for it. Missing a piece of equipment? Message Jay in the app and he'll help you find a swap.

I'm dealing with an injury. Can I still run the programs?

Not all injuries are the same, but every program in the app can be modified to meet you where you are. Rebuild and Full Body are two of the best places to start if you're getting back into training. For anything serious, check with your doctor or physical therapist first.

What if I don't have time for long sessions?

Most sessions run 45 to 60 minutes. Short on time? Bodyweight Burn sessions run 30 to 45 minutes, and the app has a library of 30-minute workouts. Jay also has videos in the Start Here section showing how to modify any workout to fit the time you have.

Will I have support if I have questions?

Yes. Every membership includes direct messaging with Jay inside the app, plus access to the JTM FIT community. Stuck on an exercise, a program choice, or a modification? Just ask.

Can I cancel if it's not for me?

Yes. Every plan starts with a 7-day free trial, and you can cancel anytime right from the app: tap your profile, then Manage Subscriptions. It takes about 30 seconds.
