In both the mens and womens professional games, the fastest backhands ever hit are all from the one handed stroke. This creates a few questions.
How can players hit harder with one hand than with two hands?
How do the pro players create this power when for many recreational players the backhand feels so weak and unstable?
Why do you never see pro players with “tennis elbow bands” on their arms and yet these are used all of the time by recreational players, and yet the pro players are hitting way harder and 1000s of times more than the rec players?
When most recreational players swing at the backhand, they push the racket forward. This puts stress on the lateral(outside) side of the arm. These smaller, weaker muscles are not designed to withstand this kind of stress. When swinging this way, the arm can feel weak and the racket can buckle under the stress of impacting the ball creating a strong possibility of injury to the arm.
