Answer for tension

Hey Hamza, this often happens on backspin shots yes, a great way to get around this is try to think about really accelerating fast through the contact of your shots. To do this you have to be relaxed, also focus on having a relaxed grip as this often causes you to tense up if your grip is too tight. Also just making sure you do a lot of practice on these irregular balls in training trying to make sure you have a relaxed loose arm.
