[boost spin]

I hear this concept of wak side & strong side in table tennis.
What does this mean ?

[Gauda 2]

With few exceptions, in almost all rackest sports & for almost all humans , forehand is the stronger dominant side & backhand is the weaker side.
Table tennis is no exception. However lot more important is the fact that table tennis si forehand dominant sport.
Unfortunately lots of amateur tabletennis players believe that they can have as good backhands as the pros , most of whom use spinverted rubbers on both backhand & forehand
