I play hockey..Welcome to the toughest sport!!
SQUAT!!! thats really important cause its the flagship for all lower body excercises it will get you some nice mass too. If you have to all of a sudden chase a player or a puck its pretty rough on your knees so make sure to pay attention to that. As far as upper body, Do some rotator cuff excercises cause 1 hard slap shot could knock it out of whack (trust me) Do some shoulder and chest routines too,
Bench press,
military press..Excercises that focus on the overall part of the muscle are the way to go. So all in all you want to get some over all mass. Squats, deadlifts, benches, military presses should keep you in good shape..Good luck and lemme know how your makin out.
