Attach a handle to the low cable pulley. Stand facing away, holding it with an underhand grip. Step forward to create tension, arm slightly behind you. Keep your elbow fixed and curl the handle towards your shoulder, contracting your biceps. Pause at the top, then slowly lower with control.
Maintain a slight bend in knees for stability. Engage your core. Keep your elbow stationary. Avoid momentum. Use a full range of motion. Exhale on the curl, inhale on the lower.
