“I became a personal trainer so that I can save you from the costly mistakes I made. I trained with improper form for years, and ran into a lot of minor injuries and plateaus. Once I cleaned up my techniques and began taking care of my body properly, I got stronger, felt better, and looked better. I want to show you how to do the same so that you can become the most elite version of yourself!”
