Curl your tailbone toward your navel as you lift the ball up zenegra 100mg low price erectile dysfunction treatment viagra, bringing your arms and shoulders up to meet the ball buy zenegra 100 mg without prescription impotence jelly. 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. ULTIMATE MAKEOVER LEG AND BUTT ROUTINE Complete the following 15-minute toning routine two to three days a week, according to the schedule provided in Your Ultimate Body Calendar, to firm, sculpt, and shrink your hips, thighs, and buttocks. 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. Bend your left leg so that your left shin and knee are rest- ing on the ﬂoor just in front of your extended right leg. Push your hips forward and 98 THE ULTIMATE NEW YORK BODY PLAN TLFeBOOK contract your abs. Prop your head with your right hand and place your left palm against the ﬂoor in front of your tummy.
