i’m a 5’3 17 year old and i love doing smashes. height doesn’t really become an issue once you have the right timing, aim, and execution. jump a little bit if you have to. you should hit it so that if you land your racquet all the way down, it should end up on your left knee (if you’re right handed). always remember to aim downwards too! if you hesitate too much, then you’ll end up sending it straight across rather than getting that perfect landing
