Stand with your feet hip-width apart, toes pointed slightly outward. The barbell should be positioned over the balls of your feet. Move your shins toward the barbell. Keep your back straight, chest up, and shoulders over the barbell.
Begin the lift by pushing through your legs, keeping your back straight. As the barbell passes your knees, extend your hips and knees explosively, generating upward momentum. Keep the bar close to your thighs, but don't allow the bar to make contact with it.
Once your hips and knees are fully extended, shrug your trapezius and simultaneously stand on your toes, then keep pulling the barbell upward with your arms to overhead with locked elbows. The barbell should be directly overhead, aligned with your midfoot, and your chest should be up.
