It's a commonly held opinion that weight training daily isn't a great idea when preparing for a boxing fight as it will make you muscle bound and cumbersome..
I've started taking a little protein shake after every training to prevent my muscle breaking down too much. I'm wondering whether or not this will affect my boxing If I increase the amount of press-ups, pull ups and sit ups I perform...Assuming the protein shake kicks in and promotes muscle growth and I increase the reps and sets I do will I actually be hurting my boxing

The question is....Under the same logic that disallows weights daily, is it a bad idea to do push ups situps and pull ups daily
