Lower your hands and the ball to the floor overhead and your legs to the floor. Repeat by using your arms to lift the ball and hand it back off to your legs. Continue to switch handing it off from your legs to your hands and hands to your legs a total of 10 to 15 times. With your tummy against the ball, grasp a small medicine ball in your right hand. Lift your right arm out to the side from your shoulder, keeping your elbow partially bent. With your lower tummy on the ball, place your palms on the floor in front of the sta- bility ball. Extend your legs behind you with the balls of your feet against the floor. Flex your feet and stretch (the proper terminology is reach) back through your heels. Without lowering your legs, spread them to a wide angle, continuing to stretch out through your heels. Without lowering your legs, bring your legs together and turn your heels in and toes out.

Resist that urge, and keep your brain in your thighs, butt, or hips at all times. Place a medicine ball against your left thigh, using your left hand to hold it in place. Exhale as you raise your left leg, pressing out through your heel as you lift and keeping your foot flexed. Bend both your hips and legs at 90-degree angles, so that your knees are on the same plane as your hips. Place a medi- cine ball against your left thigh, hold- ing it in place with your left hand. Focus on lifting with your top knee and feeling the burn in your glutes and hips. Place a medicine ball against your left thigh, holding it in place with your left hand.
