Handle: we can predict two, continental for the right hand, while eastern for the left, that we will take care to put over the right on the handle of the racket. Once the racket is held, we are ready to bring it back in a linear way and with a simple movement, keeping the arms quite outstretched and the elbows not too bent.
At the impact with the ball, it is crucial to keep the plane of the strings well, which must be facing the field. Better then to use your wrists a little, and hold them so you have the racket with the string plate parallel to the net for all the impact movement. This way the ball should come out straight with a big push and end up in the other half of the court.
Any other things to know about the two-handed backhand? If we start from scratch, it's easier to learn than the classic backhand, and "forgive" more. In the sense that it has many of the advantages of a straight and allows you to get to the ball even if we started not quite in a lightning-fast way or if the ball is very high or very low. A versatility that is not characteristic of the backhand to one hand.
Between the cons of the two-handed backhand instead, there is certainly the position of our body as a whole, more rigid than the elegance of the one-handed backhand. A few decades ago, it was said that the two-handed backhand was disadvantageous because it forced the player to get better on the ball to be able to hit it since with two hands there is less extension. Decades of champions and amateurs who have practiced the shot prove the opposite: with the backhand to one hand, flat, in topspin, you are forced to get well directed on the ball, because it must be taken by force in front of the body.
Moreover, as previously mentioned, with the backhand to two hands even arriving more roughly on the ball "playing" with the wrists and hands you can play a good shot. Important to remember for those who approach tennis, beyond the choice between a two-handed backhand or a hand, it is still essential to know how to handle the backhand with a cut hand, because that is the shot that allows you to play many of the balls out of position: too high, too low, too far.
