Got a question for ya all. My son is 11 and has been asking to go to the gym after baseball and start condition for football. Of course I am proud of the fact he wants to prepair like that at his age. My worry is, is 11 too young to do some lifting? I have read different articles that say not until 13 or 14. If I do let him lift some should I only allow machine weights? What are your thoughts/experence with this subject?
