Lie on your back with your knees bent, calves parallel to the ground, toes pointed, hands on shins. Inhale and lift your head, neck, and shoulder blades off the ground, reaching your arms toward your feet as you straighten your legs at a 45-degree angle. Maintain contact between your back and the ground. Keeping your legs together, exhale as your reach your arms overhead, then circle them out to the sides and toward your feet. Inhale, lifting your shoulder blades off the ground an extra inch, and reach for your toes. Exhale and lower your torso to the ground, bending your knees to return to the starting position. Do 10 reps.
