I went with my 19 and 15 year old sons today to workout. Today was upper body. The 19 year old just finished his freshman year of college. He is planning to be a college football coach and has had classes on exercise and putting together health plans and workouts. He is incorporating that stuff along with workouts he did when playing high school football and basketball. He lost weight when he first went to college but he has put on 10 to 15 pounds since he started working out. He is planning to help his little brother a lot over the Summer. I'm going with them. I'm not sure I will be able to move my arms in the morning.
