Inhale with torso tight. Keeping pressure on heels, dip body by bending knees and ankles slightly. Explosively drive upward with legs, driving barbell up off back of shoulders. Drop body downward and split one foot forward and other backward as fast as possible while vigorously extending arms over head.
The split position places front shin vertical to floor with front foot flat on floor. The rear knee is slightly bent with rear foot positioned on toes. The bar should be positioned directly over ears at arm's length with back straight.
Push up with both legs. Position feet side by side by bringing front foot back part way and then rear foot forward. Return to back of shoulders and repeat.
The barbell is driven from back of shoulders to arms length over head. The lift is complete when feet are in line and bar is under control. Also see movement in Slow Motion.
