Lie face down on an exercise mat with your legs extended directly behind you and forehead in contact with the floor. Bring boths hand to rest level with your chest, keeping your elbows tucked in. This is your start position. Slowly lift your torso up, keeping your hips on the floor as far as you can. Press your arms into the ground and keep your chest lifted so as not to sag between the shoulder blades. Hold this position and feel the stretch in your chest. Hold for the recommended amount of time.
