Dr. Ruben's Story
Dr. Matt Shiver
PT, DPT, CSCS, USAW-1
I didn’t grow up thinking I’d be an online coach. My journey started with physical therapy. While studying to become a Doctor of Physical Therapy, I realized I loved helping people solve real problems—less pain, more strength, and the confidence to move without fear.
But I also saw the same issue over and over again: busy professionals (especially medical staff) wanted to take control of their health, but strict diets, random workouts, and cookie-cutter programs didn’t work. They needed something simple, flexible, and built to survive unpredictable schedules.
Dr. Ruben Cabrera, PT, DPT, CPT
After years of coaching in-person and online, I created The Physique Transformation System—a clear framework that helps clients:
Lose 15–30+ lbs without tracking calories
Get stronger with time-efficient workouts
Build nutrition habits that work whether you’re eating at home, in the break room, or out with friends
Finally feel in control of food again, instead of food controlling them
What drives me isn’t just seeing weight loss—it’s seeing clients regain energy at work, feel confident in their clothes, and stop letting injuries or inconsistency hold them back.
This is the program I wish I had when I was navigating school, 30+ hour work weeks, and the doubt that I wasn’t “fit enough” or “ready enough” myself.
Now, I coach busy professionals across the country to build sustainable fitness habits that last for life.
