that's the problem with heavyweights nowadays
they all rely on arm strength, that's why they can't hit as hard as tyson

I believe I stated the importance of Legs!

Basically your whole body helps your power though, the legs are only the start, abs/back muscles help transfer that power along with chest/shoulder/arms...technique is also very important.
