”Shake hands” with the racket while the frame is pointed perpendicularly (at 90 degrees) to the court surface, just like you are shaking hands with another person. If you hold the racket on the right side (in case you are right-handed) your palm wil be behind the handle (grip), the front part is considered the one on the ball side. The wrist will be placed slightle on the right side of the butt and the formed ”V” between the thumb and first finger will be pointed slightly to the back of the handel. The left-handers will hold the racket so that the wrist will be slightly on the left side of the butt. This is the eastern forehand grip.
When you see the ball coming to you, begin to pull back the racket. This thing is done by bringing the racket back on a parallel straight line with the court surface or on a curly trajectory, first up than down. If the ball comes on the forehand side, put the left shoulder and the left foot (if you are right -handed) to the ball forming a parllel line with the sideline of the court. For the left-handers, use the right shoulder and the right foot. Use the back foot to push and transfer the bodyweight when you begin the movement to hit the ball.
At the balance movement of the racket strech your arm comfortably, but not completely. Try to carry the ball on the strings. Hold the racket tightly enough so that it doesn”t turn around when you hit the ball, but not so hard to affect your ” feeling”.
If the tennis ball has a lower waist trakectory, bend your knees, keep the back straight and do the same move.
