Back on the tennis court,. Make the normal take back.
The racket is above the ball
The left hand is on the throat of the racket
And the racket is slightly “Open”
Now instead of swinging down, throw your arm forwards as though you were “Skimming Stones” across water!
The Ball will still have slice (Because of the slightly open racket face) but it will also be fast and powerful.
This motion of swinging out into the court instead of down is fundamental in changing your slice backhand into a weapon.
Add “Skim the Stones” to your game and enjoy seeing your opponents scramble to reach your laser fast Slice Backhand
