Assume a shoulder width stance and place your hands at (or just outside of) shoulder width with a pronated grip on the bar.
Step underneath the bar and unrack it while keeping the spine in a neutral position.
Take two steps back, inhale, brace, tuck the chin, then press the bar to lockout overhead.
Exhale once the bar gets to lockout and reverse the movement slowly while controlling the bar back to just below your chin height. (This is the main difference between this and an Overhead Press).
