Aaron Marino of alpha m. has a message for all high school athletes about how to play a sport and lift weights.
Weigh training will not stunt your growth. Working out for a high school athletes is based on timing. You wouldn’t want a hard leg workout before a Cross Country meet. Save the hard leg workout for after the meet. Doing chest before a football game may make you less explosive; however, just by playing the sport or activity will loosen you up. Workout like anyone else but just be sensitive to when you workout relative to the competitive event.
