Keep torso straight but bent forward at the hips slightly.
Explosively raise the bar by extending the hips, knee and ankle in a “jumping action”.
Keep your elbows out and shoulders directly above bar as long as possible.
Keep the bar close to the body.
Once you have extended the lower leg shrug your shoulders and at maximum elevation of the shoulders start pulling with the arms.
Keep the elbows high during the pull until the highest point.
This should be a fluid motion where all the steps flow together.
