1
Stand with feet shoulder-width apart, holding a barbell with both hands at waist level using an underhand (supinated) grip. Arms should be fully extended with the bar resting against your thighs. Keep your back straight and core engaged.
2
Position hands slightly wider than shoulder-width apart with palms facing upward. Ensure elbows remain fixed close to your sides throughout the movement. Brace your core and maintain a neutral spine with shoulders back and down.
3
Slowly lower the barbell by extending the wrists and fingers, allowing the bar to roll down toward your fingertips. The movement is controlled and deliberate, with the bar rolling from your palm to your fingers. Keep elbows stationary at your sides.
4
Curl your fingers and flex your wrists to roll the bar back up into your palm, then curl your forearms upward, bringing the bar toward your shoulders in a traditional barbell curl motion. Squeeze the forearms at the top and return to starting position with control.
