so my dream is to compete next year I really am getting into bodybuilding but after working with a coach who took me in the room and have me pose for him he said that everything look good on my body but he said that they would penalize me for bad hamstrings. he gave me some tips to improving my hamstrings but said at the end of the day it was genetics and there wasn't much he could do from there. My question to you is this anyone suffer from Bad genetics with hamstrings and how do you improve anyway I don't buy his answer
