    Grip Types for Holding a Table Tennis Paddle

    In high-level table tennis, there are two main grip types, the shake hands grip, and the penholder grip. Each of these two types has several variations, which we will look at in detail.

    Table Tennis Grip

    So, as I said earlier, the table tennis grip is important because it controls the angle of the racket, which in turn controls the height of the ball, the depth of the ball, the speed of the ball, the direction of the ball, the type of spin and the amount of spin. Here's a video demonstration of the shake-hands table tennis grip.
