How to add more power to twist serve? Now I have my twist serve match ready (don't have to practice for an hour everytime to re-learn it everytime). I wonder is there a way to make it more powerful (speedy). I am tossing more into the court already, I have use better weight transfer (back leg to front leg), I use square stance. It goes like flat serve (until it bounces of course). I have tried to hit it with 100% strength, and it is a lot faster (flat serve fast), but I cannot sustain that for a set let alone a match. Is is impossible? My friend just commented on my serve the other day, he said he saw a slice serve coming, so he was going to his FH, then the ball bounce and go to his body. Nice feeling to have a twist serve .
