Tennis Ball Machine at AVAC

 Reviewing the Gopro Hero7 video of my tennis strokes, I observed the following errors:

 

1. Forehand
• Use a wider stance (should be sitting down)
• Not twisting enough before ball contact
• The left (non-playing) hand drops down during the stroke
• Stand on your toes (not flat-footed)
• Move more
2. Two-handed backhand
• Preload (twist) more
• Start with the racket high up, before initiating the loop
  
3. One-handed backhand
• Stay sideways through the shot
  
4. Backhand Slice
• For more power, you can hop forward on the front leg
• Use continental grip (bevel 2 on the index knuckle)
• The ball will travel in the direction of the racket (chopping low, and the ball will go low)
5. Volley
• Do not swing the racket
• Hit the ball before the foot touches down
  
6. Serve
• Racket drop is still incorrect
• The right arm should be palm down during the beginning of the swing
