Stand tall with a neutral spine and your feet shoulder width apart. Grip a weight plate securely in your hands with your arms extended by your hips. Brace your core, keep a neutral spine and look straight ahead as you extend your arms directly out in front of you, and bring the plate level with your shoulders. This is your start position. Begin to twist the plate from side to side as if it was a steering wheel. Be sure not to let the plate drop lower than shoulder height. Repeat for the required number of reps (or time).
