One

Starting Position: Place a barbell in a rack at approximately shoulder-height. Grip the bar with the hands just wider than shoulder-width apart and dip under the bar to bring it off the rack. Step backwards with the bar resting across the front of the shoulders. 

Two

The palms should be facing the ceiling and the elbows pointed straight ahead but slightly in front of the bar. Quickly bend the knees while keeping the back straight and the chest tall. Keep the heels in contact with the ground until you explosively drive the feet into the ground to send the bar directly upwards overhead. 

Three

Your feet should move outward about 1-2 inches. Once you are able to gain control and balance, stand up by extending the hips and knees to a fully erect position with the feet now flat on the floor.

Four

With the bar still overhead, move such until there could be a straight line down to the middle of your feet. 

Five

Adjust your feet back to shoulder-width apart, need be. Then lower the bar back down to shoulders, assuming starting position, and then repeat.
