Exercise Advice: One of your hands will be extended out in front of your body at about waist-level. The other hand will be at your side at waist-level as well. Slowly extend, or ‘kick back,’ the hand that is at your side while keeping that same elbow firmly set in place. Extend your arm back to a point where your elbow becomes completely locked out. It is very important to keep the lead hand that is out in front of your body in a firmly set position throughout this entire exercise. Be sure to squeeze your triceps at the top of the movement and hold for a one-count. Repeat with other arm.
