I think I posted my last message to you in the wrong place. My son just started track practice (which he has never competed in before) because he has always played football and basketball. However, the track coach is encouraging him to try the discus throw,the javelin throw and the high jump. I am not happy because all I want him to do is to be in shape for runnng, situps, pullups and pushups. I don't want a new injury after he just got the medical waiver on Friday. Any suggestions? Thanks.
