After suffering a severe bicep injury while strength training, Bill DeSimone took it upon himself to look where few personal trainers and fitness “gurus” have before – anatomy, physiology, and bio-mechanical text books. What he found was simple, yet profound: many popular exercises thought to be “safe” and “effective” were in fact in direction contradiction with proper muscle and joint function as the science geeks would have it.

The result of this discovery was the Moment Arm Exercise manual that took the internet by storm. At this point Bill is arguably the world’s leading authority on the often overlooked yet critical bio-mechanics of exercise, which when used to your advantage, can dramatically increase the safety and effectiveness of your workouts – now and for the long haul.
