hey guys, today i was just practicing my serves as usual. then all of a sudden the thought of weightlifting came into my mind. when i exhale during my squats and bench presses i can lift faster and with less effort than usual. so i tried to incorporate this into my serve what i did was i would inhale really slowly while bouncing the ball to reset into my service stance, and once my breath was full, i would just serve normally but exhale before i hit the ball. my second serve was much more consistent and kicked higher. my first serve was more consistent and maybe a little faster. what do you guys think? is it in the mind? or does this actually work? even if you think it's crazy, just try it!
