Attach a handle to a low pulley. Stand facing the machine, feet shoulder-width apart. Grasp the handle, palm forward, and create tension. Keep your upper arm stationary and elbow close to your torso. Curl the handle up, contracting your biceps, and pause at the top. Slowly lower the handle back to the start, controlling the movement. Switch arms after completing the set.
Maintain a slight bend in your knees for stability. Avoid body swing and momentum; focus on controlled movements. Keep your wrist straight and relax your shoulder throughout.
