Place a barbell on the floor and position yourself over the center of it with your feet shoulder-width apart and shins about 1 inch away from the barbell.
Maintaining a straight back, bend down with your legs while leaning forward and position your hands on the barbell shoulder-width apart with an overhand grip and fully extended arms.
Exhale and push through your feet while extending your legs to begin lifting the barbell while maintaining a flat back.
After the barbell passes your knees, drive through your hips while continuing to extend your legs until you are standing fully upright with your torso in line with the rest of your body. Do not lean further back than this.
Inhale and begin to lower the barbell by bending your legs and lowering your torso while focusing on maintaining a flat back above all else.
Returning to the starting position, rest the barbell on the floor for 1 second before beginning your next rep.
