After training w/ Aaron for the summer, I was noticeably stronger, faster & slimmer. His confidence in his abilities brings a certain spirit that helped motivate me when I really didn’t feel like going to the gym. Aaron’s knowledge in health, fitness & the human body is unmatched, in my opinion. He’s well versed in training & supplementation to maximize the results of training. His goal is to get you in the shape you desire while keeping you as healthy as possible.

He’d always assess how I’m feeling before each training session to make sure we’d get the best training possible while working around previous injuries, aches & pains. He takes his craft very serious & I highly recommend him to anyone not only because he’s so well versed in what he does but because he understands our needs being in the film industry. It’s not easy to find someone like him.

— Anthony Katagas

— Ray Park

"Training with Aaron was the first time I really understood what intensity feels like. He helps you dig deeper & push harder. Not with an overly aggressive approach — but by making you believe in yourself & find that will to do better."

— Oliver Stark

"What a great training experience! It was pretty cool to see the physical changes come in without having to starve myself. Aaron's a miracle worker!"

"I never imagined when we started this program, how much I was going to be pushed to my limits. never imagined I was going to be able to do so many workouts and gain so much strength.

Brother, I thank you for the sea of knowledge you provided and the tools you gave me to be better and healthier, physically and mentally. These tools will be useful for the rest of my life!"
