9. Hanging leg raise

(for abs)

Find a playground bar low enough that your feet touch the ground when you're holding onto it. Grab onto the bar, tighten your ab muscles, and slowly bring your knees in toward your chest (as shown at left), keeping your back straight. Return to starting position as slowly as you can. Do 15 reps.

10. Walking burst: Speed intervals
Alternate walking 10 seconds at a moderate pace with 20 seconds at a fast pace, for a total of 2 minutes.
