should I rest a day after hitting serves?
I thought about this in comparison to baseball: a starting pitcher will only throw hard once every five days, and rest his arm the other days.
How is serving in tennis similar or different to this?
Would I benefit from not hitting serves on consecutive days?
How much rest does someone's arm need after hitting serves?
I have noticed that my arm felt a little more lively when I had not hit serves, or played tennis in the previous days.
What is your experience?
