Leo Hamel Sr. in 1951

Leo’s Fitness Lab is dedicated to my father, Master Chief Leo Hamel Sr. (seen above) who served as a Frogman in the Navy’s Elite Underwater Demolition Teams, the direct predecessors to modern day Navy SEALs.

As a competitive bodybuilder, my father taught me the importance of weight training for fitness and fat loss. I’ve carried this knowledge with me throughout my life.

I previously worked out with weights, aerobic machines, and took classes at traditional gyms but never quite achieved the results I was looking for. I lost weight, but lost muscle as well as fat, so I simply became a smaller version of my old self. Sure, I wore a smaller pant size, but I was “skinny fat.” I never achieved the chiseled body that I desired. After reading the book, Body by Science, I discovered the reasons why I was failing.

I searched for, and found, the scientifically based technology that was necessary to achieve my goals and brought them all together in one place. I’m so excited to share this revolutionary technology with all of San Diego! 

I believe so much in our combination of high-tech focused exercise equipment and targeted personal training that it’s the only workouts I do now.
