STARTING POSITION:
Stand straight with your feet shoulder width apart. Select the appropriate plates amount to put them on the bar. Take the bar with a prone grip behind your back and with your arms extended. Your hands should be slightly wider than shoulder width. Contract your pelvic floor and core while keeping your chest up.
MOVEMENT:
Fully extend your wrists with a smooth movement. Raise the bar bending your wrists. Make sure you only move your wrists.
TIPS: The exercise key is quality over quantity. The trick is to perform the exercise using proper form.
