1
Stand with feet shoulder-width apart, knees slightly bent, holding a barbell with an underhand grip (palms facing forward) at arm's length with hands shoulder-width apart. Maintain neutral spine and engage core.
2
Position the barbell at thigh level with elbows tucked close to the torso, shoulders relaxed and slightly retracted. Ensure a firm grip on the barbell with wrists in neutral position.
3
Lower the barbell in a controlled manner by extending the elbows, allowing the weight to descend toward the thighs while maintaining elbow position close to the body. Continue until arms reach near-full extension without locking out elbows.
4
Flex the elbows and curl the barbell upward by contracting the biceps, driving the elbows upward while keeping them fixed at the sides. Raise the barbell to chest level, squeeze the biceps at the top, then return to starting position.
