Movement: Bend over, hinging at the hips while keeping a neutral spine. Brace yourself with one arm on a sturdy object. Keeping your working elbow next to your body and your upper arm parallel to the floor, extend your forearm behind you. Return to the start position slowly until your forearm forms a 90 degree angle with your upper arm.
Emphasis: Do not allow the elbows to flare out to the sides when performing this movement. Focus on contracting and flexing the tricep. Without weight the strength of your contraction will provide the resistance.
