Here's a dynamic exercise to help you develop flexibility and strength without risking injury or building bulk. You'll increase your upper body strength while stretching the backs of your legs.
-- Karen Voight
1 Kneel with your forearms and palms of your hands on the floor, shoulder-width apart. Spread your fingers, pressing down firmly with your index finger and thumb. Straighten your legs then walk toward your elbows until your heels are close to the floor and your knees are straight. Be sure to push against your forearms and keep your shoulders away from your ears. Do not collapse into your neck and upper shoulders. Pause for three breaths.
