Thanks. Would using almost only wrist help as my current motion is forearm with wrist snap?
post a video of you serving.
My guess is you are making too much of a "hit" with your serve, instead of a brush.
a couple other things:
1) make sure the first contact of the ball is near the front edge of the paddle.
2) make sure you're stroking the ball in your "strike zone", which is generally in front of and slightly higher than your bellybutton
3) focus on the wrist snap, but eventually to have a truly spinny serve, you have to have your torso movement as a part of the overall serve motion. Your body has to twist as the same time as your wrist snaps. This timing takings thousands and thousands of times to practice and solidify the technique.
I also want to say that conceptually, your serves are probably easy to return NOT because they are not spinny, but probably because they are predictable. Someone can have the most underspinny serve in the world, but if i know its super underspin, i can simply keep my paddle flat and low, meet the ball right at the bounce, and touch the return short. Likewise, if i know your serve is pure sidespin, all I have to do is adjust where I am aiming my return, and I can unload a loop or a flick to easily return with quality.
The best servers are the ones who can vary the; SPIN and PLACEMENT of their serves using the a similar serving motion. Your pendulum serve becomes a million times more effective if I think its heavy backspin when i'm returning but its actually dead. or I think its a underspin serve but its actually topspin.
Hope that helps! my final tip, if you really want to get better at serving, you have to practice with a bucket of balls for at least 20 minutes a day. Do this for even just a month and you will see a positive effect on your serves.
