To begin this movement, start by holding the bar on your upper chest with your grip just outside of shoulder width. Take a deep breath, and strongly brace your abdominals and lower back.
Begin by pressing the bar overhead while maintaining a tight core.
Once the bar is just over your head, lock your elbows out and bring your head through so that the bar is above your head at the top of the movement. As you lower the bar, do so in a controlled manner all the way down until the bar is resting on your chest. Reset and start the second repetition.
