I build the tools I couldn't buy.
I'm Michael Kamalu, founder of Dr. Gains. I trained at the Mayo Clinic School of Medicine on a full scholarship, published research alongside a professional sports team's orthopedic surgeon, and left medicine to build three seven-figure companies in health and fitness.
For years, the same problems showed up in my own training and my audience's: grip gave out before the target muscle did, and there was no real way to load rotation. So I spent three years and seventeen prototypes designing the Gains Hammer myself. Over 260,000 people follow the research on YouTube, including thousands of physicians, therapists and coaches.
