Brace your core and keep your upper arm still. Extend your elbow, straightening your arm overhead and squeezing your triceps. Inhale as you slowly lower the handle behind your head, maintaining control.
To protect your shoulder joint, keep your upper arm stable and close to your head throughout the movement, preventing any rocking or swinging. Focus on squeezing your triceps muscles at the top of the extension to maximize muscle engagement and ensure proper form. Lower the weight with control, resisting the pull of gravity to build strength and avoid momentum, and remember to brace your core to stabilize your body and prevent lower back strain.
