What is the first step when teaching a stroke?

Pros, generally the first step is to show someone the grip show them where their hand fit or position on the racket handle. This show the student the proper hand position. Step two, you need to demonstrate the ready position, this demonstrate how we wait, step three, demo the entire swing, set up with a turn, or pivot, the racket, travels back and down to the bottom of the backswing, and then the contact point, and the fall through, and recovery. the key is student needs to see visually the mechanical characteristics of the stroke. Let say, if it’s the forehand; you need to demonstrate that so they can understand visually what the goal would be. This is how we demo and explain on the USPTA professional exam. I hope your pro does this!
