Children and exercise--the gym or outdoors?

I go to Lifetime Fitness (I call it the gym) about 5x a week. Sometimes parents bring their children--I think they need to be 12 to be a guest. They are well-behaved and no trouble--but I do feel sorry for them, especially the young girls who are probably already a little over concerned about their bodies.

No one wants to hear that we knew better in the "old days" but here it is. I hated school PE classes, I admit it. I did avoid all organized summer sports although the town had community leagues. But I certainly had a lot of exercise. Watching a little kid on one of those machines today I recalled:

• climbing trees
• riding horses
• biking on no-speed, manual brake bicycles
• playing hop-scotch
• raking leaves in the fall
• mowing the lawn in the summer
• pulling weeds in the garden in the summer
• digging dandelions in the yard in the spring
• running during recess
• swinging on the monkey bars in the school yard
• roller skating with strap on skates on the sidewalks
• catching tadpoles and frogs in creeks
• playing softball in the street with neighborhood kids
• delivering newspapers on a morning route
• running just because
• and we walked because our mean mothers wouldn't drive us everywhere we wanted to go!

Most of these with the exception of newspaper delivery were social activities--done with friends or a group.
