Stand with your feet hip distance apart with a weighted barbell in front of you. Hold barbell with your hands just outside your legs in an overhand or mixed hand grip. Keeping your legs and arms straight, begin to hinge at the hips lowering the bar. Maintain a straight back and keep your knees in the same slight bend you started with. Inhale and lift the bar by extending your legs and squeezing your butt. Continue, repeating the motion.
