Bruce Lee trained primarily for strength, power and speed - his physique is simply a byproduct of the long and dedicated hours that he put into martial arts training. In addition to lifting weights, his daily training journal indicates that he punches up to 1000 times a day, 500 finger jabs, 1000 kicks, flexibility, agility & endurance work and trying out new routines, theories, systems and methods.
If you want his physique, you'll need his genetics and follow his daily training routine for a few years, spend countless hours choreographing and staging fight scenes in the extremely humid climate of Hong Kong.
