I'm trying to learn topspin serve and still take 1 - 2 hours lesson for 4-5 times per week.
What I notice is that after hitting a bucket ~100 balls ~ 20-30 minutes, i start to get some fatique and my body gets stiffer. Even though the coach told me to relax my hip, my shoulder, i could not.
Just afraid that there will be diminishing return or even to the point of negative return if I keep serving with a stiff body, that may hamper the technique.
On a side question, anybody do topspin smash at baseline if the opponent lob deeper to the baseline? Should i try to do that?
