Teaching Body Rotation as Part of Footwork

My conventional approach in teaching the stroke-footwork for back court overhead shots is like this:

• footwork to the back (either steps or chasses, emphasis on a side-on position moving back)
• stroke (initiate with body rotation)

However, some common errors are:

• moving back facing the net
  

There are a couple of issues here. First of all, it is difficult to push off quickly moving backwards. Even if you do manage to generate some speed, there is a risk of tripping/falling over, or at least there will be difficulty/slowness in stopping yourself once you arrive at the back. Once you reach the back, your body will not be in a position to use body rotation to initiate the shot.

• initiating stroke with shoulder rotation instead of body rotation

Obviously, it is desirable for movements to occur from the proximal to the distal ends -> in this case body rotation to shoulder rotation. When shoulder rotation occurs first, it can "drag" the body into rotation, reducing the power delivered through the arm and into the racquet.

Proposed solution:

It may be helpful to separate the body rotation out of the start of the stroke movement, and into the end of the footwork movement. Instead of coaching

(right left right) + (turn & swing)

You could use

(right left right turn) + (swing)
