For Tennis, One of the muscles that you really need to make stronger so you can hit and play better is your forearm.
You Can Do a Few Things to make This Stronger
-First
You Can just get a tennis racket and do “ups” and downs”
hitting the ball on your racket. Also try different grips, ie serving grips because that’ll make it better too along with your serve.
-Second
You Can Get one of those Hand Scrunch things. I forgot the name but its the thing that looking something like / and you scweeze.
Third-
By throwing baseballs, there heavier and this will make tennis easier
Fourth-
Also you should be able to be quick so springs would be good, even long distance to help your stanima
Good Luck-
