1
Lie prone (face down) on a flat surface or bench with your body fully extended and legs straight. Position your upper arms parallel to your torso with elbows flexed at approximately 90 degrees, hands positioned near your shoulders.
2
Engage your core and maintain a neutral spine. Keep your upper arms stationary throughout the movement with elbows firmly positioned to prevent shoulder movement. This is an isometric starting position for the exercise.
3
Slowly lower your body by extending the elbows, allowing the forearms to straighten and the body to descend toward the ground in a controlled manner. Maintain upper arm position and control the eccentric phase for 2-3 seconds.
4
Press through your palms and contract the biceps to curl your body back up, flexing the elbows and returning to the starting position. Drive the movement by pulling your chest toward your hands while keeping elbows stationary.
