1
Stand upright with feet shoulder-width apart, holding a curved barbell with an underhand (supinated) grip at arm's length in front of your thighs. Keep your chest up and core engaged.
2
Position hands slightly wider than shoulder-width apart with palms facing forward. Ensure elbows remain stationary at your sides throughout the movement.
3
Lower the barbell in a controlled manner by extending your elbows, allowing your arms to fully straighten. Maintain upright posture and avoid swinging the weight.
4
Curl the barbell upward by flexing your elbows, bringing the weight toward your shoulders. Squeeze the biceps at the top of the movement, then return to the starting position with control.
