The cable kickback is a single-joint isolating exercise that increases strength in the triceps.
Assume a staggered stance with one foot forward in front of a low pulley equipped with a single-handle attachment. Bend at the waist and support your weight with the front hand on your front knee. With your other hand, grab the handle and bring your elbow up so that same upper arm is parallel to the floor.
Pull the cable behind you by contracting the triceps and without moving the upper arm. Pause for one second at the top and then return to the start position.
Keep your head stable and your chin parallel to ground throughout the movement.
Keep your elbow stationary and tucked at your side.
