I don't understand this answer. Phase 5 is In-Season Maintenance.I guess I should have given you more details. The program is for my high school son, he will be 17 in October. According to the program in August there are no workouts. He does not play any fall sports. Is there anything he can be doing right now? He want to improve his pitch speed by the next season which begins in late February. Should we just start with Phase 1 and go by the college schedule?
