Anchor the band to the highest point possible. Reach overhead and grab the handles with an underhand, shoulder-width grip. You'll probably need to kneel down on the floor to create tension in the band, unless you have an extremely high anchor point. Your arms and shoulders should all be in a straight line overheard. With your body stationary, curl from overhead to behind your head. Focus on curling using the biceps and reaching a controlled contraction just behind the top of your head.
