Proper weight transfer: Load up the right leg in the unit turn. Then, precisely at impact, shift weight upwards, thru and into on-coming ball ...do not shift weight onto left side before impact
Note the torso is inclined to the right ..you can see it clearly via the shoulder line ..this imparts heavy topspin when combined with the low to high swing path
note the use of the left arm in a "yes !!" inward pull ...this is a effective way to start the upper torso rotating (in tandem with the aggressive hip turn) and create massive arm lag
