Can't generate headspead with bh grip for twist-serve.

[djones]

I somehow don't understand why I can't generate headspead when using a bh grip for the kick service.
I kinda swing my racquet very stiff.
It feels kinda wrong the way I hold my racquet.
What's my problem?

your problem is you're not going through the ball..

the twist serve is a combonation of stricking UP and FORWARD.. if you simple go up, you'll get twist, but not much kick and the ball wont penetrate.

Relax those wrists throughout the swing!
