1
Stand with feet shoulder-width apart, knees slightly bent, holding a barbell with an underhand (supinated) grip at arm's length by your sides. Maintain an upright torso with shoulders back and core engaged.
2
Position hands slightly wider than shoulder-width apart with palms facing forward. Keep elbows tucked close to your torso throughout the movement. Ensure the barbell rests comfortably in your hands with a firm grip.
3
Slowly lower the barbell back to the starting position by extending your elbows in a controlled manner. Allow your arms to fully straighten at the bottom while maintaining slight tension in the biceps. Keep elbows stationary and avoid swinging the weight.
4
Drive the barbell upward by flexing your elbows, curling the weight toward your shoulders. Keep elbows locked at your sides and focus on squeezing the biceps at the top of the movement. Return to the top position with controlled momentum.
