Bruce Lee’s way of Jeet Kune Do 2018

Bruce Lee’s power was in his tendons as well as his muscles. Most of Bruce’s power (speed and strength) was tendon power, not muscle size, and was developed through stationary (i.e. isometric) “motion”. With a body weight of around 135 pounds, it is reasonable to assume that his speed and strength did not come from large muscles.  In fact, his superior power (speed and strength) was very disproportionate for someone his size. The isometric power that Bruce had is what is known as sinewy power, which means strong-like tendons.
