Is resistance training a matter of being gifted or having good genes?

The general consensus takes the cake here! Of course resistance training has nothing to do with genes or gender. Recovery and physical adaptation to exercise, however, are largely influenced by genetics (distribution of muscle fibers like Daniel said, for example). So we may could say that one’s capacity to benefit from resistance training can potentially be limited by these factors (genes and gender).

Excellent point made here, Leondro!
