In these videos the racket is above the head just prior to the downward & forward swing.
In your stroke, the racket is about at your waist height.
In my opinion, there is probably a biomechanical advantage for getting the upper arm (humerus) up
somewhat - it stretches the largest muscle attached to the arm, the lat. Forehand too.....
i tried to fix long time ago but no progress. Any tricks?
