Start by adjusting the pivot point to be at shoulder height. Adjust the handles on both sides to be as low as possible. Hold both handles and stand with feet shoulder width.
With a slight bend in your arms bring your elbows upwards to approximately shoulder height. Then slowly retract to just before the start position. Maintain a consistent bend in the elbows throughout. Your elbows should stay roughly in line with your hips on the way up and down. Repeat for the desired amount of repetitions.
Avoid hanging from the hips to help raise the weights upwards or lifting your hands too far above your shoulders.
Fitness for all, for life.
