New Mom Circuit-Style Workout

Warm up: Go for a brisk 10-minute walk or do the following for 1 minute each, then repeat: march in place while pumping your arms; lift your knees and touch the opposite elbow, alternating sides; move each foot from side to side, tapping the opposite foot.

Cool down: Lunge with your right leg in front and knee bent, your left leg behind you and straight. Raise your arms over your head and hold the stretch for 30 seconds. Switch sides and repeat.
