The World's Single Best Stretch
If I have time to do only one stretch, what should it be? — Ricardo S., Hoboken, NJ
Do the "Forward Lunge, Elbow to Instep," which is known as "the world's greatest stretch" because it hits nearly every muscle in the body. It also creates symmetrical strength and stability, which helps boost athletic performance.
Step forward with your right leg, as if you're doing a lunge, and place your left hand on the floor. Move your right elbow to your right instep; hold for two seconds. Place your right hand on the ground and rotate your left arm and chest toward the sky; hold for two seconds. Place your left hand on the floor, move your right hand to the outside of your right foot, and push your hips toward the sky, pulling your right toe toward your right shin. Step forward into the next lunge with your left foot and repeat the process on your left side. That's one rep. Do five.
