Lie on your back with your legs up and bent at 90 degrees—thighs straight up and calves parallel to the floor. Rest your hands at your sides, palms down. Keep your abs contracted and press your lower back toward the floor.
Inhale and lower your left leg for a count of 2 (“down, down”), moving only from your hip and dipping your toes toward the floor (without letting them actually touch it). Exhale and raise your leg back to the starting position for a count of 2 (“up, up”). Repeat with your right leg and continue alternating until you’ve done 12 reps with each leg.
Lie on your back with your legs extended along the floor. Raise your left leg toward the ceiling, with toes pointed and hands at your sides, palms down. Hold for 10 to 60 seconds. (If this position is uncomfortable, you can bend your right leg and place your right foot flat on the floor.) Make a small circle on the ceiling with your left toes, rotating your leg from your hip. Inhale as you begin the circle and exhale as you finish. Keep your body as still as possible—no rocking—by tightening your abs. Do 6 circles, then reverse direction for six more. Repeat with your other leg.
Start as in the Toe Dip but with your hands behind your head, elbows out to the sides. Curl up to raise your head, neck, and shoulders off the floor.
As you inhale, rotate your torso to the right, bringing your right knee and left shoulder toward each other and extending your left leg toward the ceiling in a diagonal line from your hips. As you exhale, rotate to the left, bringing your left knee toward your right shoulder and extending your right leg. That’s one rep. Do 6 reps.
Lie on your left side with your legs straight and together so your body forms one long line. Prop yourself up on your left elbow and forearm, lifting your ribs off the floor and your head toward the ceiling. Place your right hand lightly on the floor in front of you for balance. (If this position is uncomfortable, extend your left arm on the floor and rest your head on your arm.) Raise your right leg to hip level and flex your foot so your toes are pointing forward.
Exhale as you kick, swinging your right leg forward as far as comfortably possible and pulsing for 2 counts (“kick, kick”). Inhale, point your toes, and swing your leg back past your left leg. That’s one rep. Do 6 reps without lowering your leg. Then switch sides and repeat.
Back Extension with Rotation
Lie on your stomach with your forehead on your hands, palms on the floor. Separate your feet to hip width. Pull abs in.
Raise your head, shoulders, and chest off the floor. Rotate your upper body to the right and back to the center, then lower. Repeat to the left side and continue alternating until you’ve done 6 rotations to each side.
Sit on your left hip with your left leg bent in front of you and your left hand beneath your shoulder. Place your right foot flat on the floor just in front of your left foot so your right knee points to the ceiling. Rest your right arm on your right knee
Pull your abdominals in, press into your left hand, and lift your hips off the floor. As you come up onto your left knee, straighten your right leg and raise your right arm over your head so you form a line from your right fingers to your right toes. Hold for 10 to 30 seconds. Lower and repeat on the other side.
