The Game Plan: Do this workout two to three times per week, resting a day in between to let your muscles recover.
You'll Need: A walking area outdoors with staircases or benches along your path. A school track that also has bleachers is a great option.
Warm-Up: Walk for five to 10 minutes at an easy pace to prime your body for action.
Circuit: Do one to three sets of each of the following moves, interspersed between walking bouts of two to three minutes. Walk at a moderate pace; you should feel slightly breathless. During the lower body moves, especially the stair climbing, you'll be working even harder.
Cooldown: Walk slowly for five to 10 minutes.
