As of tomorrow, my son will be 11-years-old. Ack! (Why does 11 sound so much older than 10?) In any case, he's old enough that when we visit the playground, he doesn't need my assistance. In fact, he'd much rather I sit quietly by -- there if he wants to show me some cool new stunt, but not in his way as he's making new friends.

Typically, I just bring a book and use playground time to unwind a bit. But maybe I'll use the time to be a bit more active now. Women's Health Magazine has four great exercises you can do at the playground:

• Use the swings to work your glutes, hamstrings, and quads.
  
• Monkey-ups work your biceps, core, and back.
• The Bench Jump is a great cardio move that works your core, glutes, hamstrings, and quads.
• A swing makes this modified push-up an effective shoulder, bicep, back, core, and chest workout.
