Serve -pronation and supination

Il Ill Asked 10 years ago

Master Rosario,

When profi players use more spin on the serve , they use pronation and supination with forearm?

Or only move with wrist?

Thank you in advance

Hi Il,

There is some movement through the forearm as well.  However, if you focus on the wrist coming through you will find the forearm will also turn with the motion.
