Some interesting thoughts that I could try – from an online source:
The free leg should come forward and then up, like you are drawing an upright CCW circle in the air with your free foot (like pedaling a bike backwards). Keep your left arm strongly checked in front even before you step onto the LFO-3, and keep it in front during and after the turn. You should bring your right knee up to meet your left hand in front of your torso.
The right knee driving upwards is the key to getting good height.
Your free foot should go a little forward, and then up, kind of like tracing a backwards J in the air.
