Upper Body―Part 4
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: Doorjamb Chest Stretch (stretch)
Stand near an open doorway with right elbow bent, as if swearing an oath. Place right palm on doorjamb, and slide it up slightly. Slowly lean forward into door opening until you feel a stretch in chest and front of shoulder. Hold for at least 15 seconds, then repeat on the other side.
