If you only keep one thing in mind in all of the pickleball you play, it’s ‘keep everything low.’ If you pop a ball high above the net, you, or your partner are going to be in a bad situation.
There are exceptions. Serves and returns of serve can be high and floppy, as long as they land deep, near the base line.
Lobs give you time to reset, to get back to the kitchen.
However, if any shot after the second one, which has to bounce before it can be returned, is high, expect trouble. This is even more true if the high shot lands behind the kitchen line.
So how do you keep every shot low? Practice is the main thing. Additional techniques that will help are to stay calm, and get low. Bend your knees. I’m not sure of all the dynamics, but when you get low, your accuracy improves tremendously.
