Abs―Part 4

Minute 8: One-Leg Bridge (toning, pictured)
Lie on back with knees bent, feet flat on floor, and arms by your sides. Raise hips off floor as high as you can. Now straighten left leg (make sure hips remain level, and keep weight on shoulders, not neck). Hold for a count of three; lower to start position. Repeat for 30 seconds, then switch legs.  

Minute 9: Stair Climbers (cardio cooldown)
Run up a flight of stairs as fast as you can, then jog down. Repeat for 30 seconds. (If you don’t have stairs, do the Sideways Shuffle.) Then walk in place for 30 seconds to slow your heart rate.

Minute 10: Cobra (stretch)
Lie facedown with palms on floor near shoulders and elbows close to body. Press hands into floor as you lift upper body, keeping hips on floor. Relax shoulders, and look straight ahead. Hold for 30 seconds.
