How do create backspin on your serve?

Answer 1

I am not trying to be a jerk here, but I think you are either talking about slice or top spin serve. I have never heard of or seen a backspin serve. Anyway the way you create spin on your serve is related to how you have the racket angled and attack the ball. For both serves you have to hit with an eastern or a continental grip, I am going to assume you know what they are , but if you do not, you can google tennis grips and get a picture of them. Now when I teach( assuming you are a righty , just reverse this if you are a lefty) the slice serve the toss should obviously be high , high enough that you can hit the ball on the way down. You start off by hitting the back of the ball and then slide your racket across the right side of the ball ( a visual that has helped some students is thinking the ball is a head with the face looking at you ) and cutting the right ear off to make it break to the left.
The top spin serve you make toss strait up slightly behind you, you bring the racket up with the right hand side of your racket is on its side and pointing to the sky. Then try and make it so as many of your strings as possible brush up across the ball so that it spins end over end in a upward motion so that upon hitting the ground and bounces, the bounce is strait up.
The kick serve you toss a bit to your left so you arch your back at bit and brush up the left side of the ball, again aiming the top of your racket which is on it side with your wrist bent , at the bottom of the ball, but this time hitting the left side of the ball. This will cause the ball to hit the ground and explode to the right.
Now on all the spin serves you use the same racket speed ( or swing as hard) as you would on the first serve , for several reasons the one of the main one is that it keeps you from choking (double faulting) and it will go over the net with much more net clearance ,then the flat serve , thus giving yourself more margin for error.
When you start learning these serves you will hit a lot of mishits or in the tennis world what you would call a shank. You just have to expect this and not get to frustrated that you give up. I know this did not answer what a backspin serve is , but I do believe that you may have just had the wrong term, and what I have written is of some help or unfortunately we just wasted each others time , good luck.

the best way to do it to toss the ball up and come down with a slice... it's really hard to explain and is much easier to watch and learn. ask someone who knows how to play if they can demonstrate... or just watch the professionals and try to imitate them. it takes practice but is most definitely worth it in the game.
