Jack Shangold, personal trainer

Jack Shangold

Some kids had a sport. I had a Bowflex in the basement. I was 10 when my parents put it down there, and from the first time I picked it up, something settled in me. The gym became the place where I understood myself best, and I spent years teaching myself what my body was capable of.

By college that curiosity had turned into something serious. I was competing in powerlifting, chasing numbers I once thought were impossible, and the stronger I got, the more people came to me for help. Those conversations meant more to me than I expected. What lit me up was not only my own training, but helping someone else find that same spark, so I decided to build a career around it.

In the beginning I worked only with competitive athletes, coaching lifters and sport athletes to the highest levels of their game. I loved the precision and the pressure of it. But about three years in, I started taking on everyday clients, and that is when everything changed for me. Watching someone grow stronger and feel it ripple into the rest of their life, their confidence, their health, the way they carry themselves, moved me in a way competition never had.

That feeling is why I am still here. Today I coach clients from 10 to 86, every background and every goal, and I still get chills when someone realizes just how capable they really are.
