Q: What do you think of a 10-year-old boy lifting weights?
A: If your son's interest in lifting weights is founded in a desire to look like Arnold Schwarzenegger or Bo Jackson, he'll be disappointed. At 10, his body is not yet secreting large enough amounts of testosterone to produce significant muscle growth through weight lifting.
Nonetheless, boys can improve muscle tone and increase strength by lifting weights. It is important the regimen not be excessive; tired muscles are more prone to injury. Your son should never lift alone since a dropped weight can lead to serious injury.
