It is true you have to keep athletes happy, because bottom line is, wether you give them an exercise or not, if they want to do that exercise (or muscle group), they will.
So, it's better to have beach muscle exercises worked into a program properly because if you don't, before you know it they will be focusing on these muscles.
So bottom line is you give your athletes a few curls or bench presses per week and its enough to keep them happy.
