Stand with your legs about 3 feet apart, feet and toes pointed forward. Lower your body to a gentle squat, then bring your right foot diagonally behind your left leg and touch your toe down. Hold for one second, then fire up your glutes and push off your left foot in a jumping movement to the right. Bring the left foot diagonally behind the right, then repeat on that side. Continue to push left and right for 30 seconds—about 15 to 20 reps total.
