There are three videos and they are all quite useful. The important take-aways are:
- Go down (knees bent) and up (knees extend) on your groundstrokes for power.
- Turn fully (off arm parallel to baseline) on groundstrokes for power.
- Hit through the ball (extension) for depth on groundstrokes.
- Slow things down and do shadow swings to teach your body the right movements.
