Start with your feet hip-width apart and a slight bend in your knees. Lean forwards at the hips until your torso is about 60 in relation to the floor, maintaining the natural arch in your back and keeping your abs tight. Grasp the barbell with an underhand grip, with your arms hanging straight down from your shoulders.

Lift the bar towards your belly button, your elbows close to your sides on the way up. Slowly return to the starting position and repeat.
