( respectfully ) You older student looks like he has an old untreated or
chronic shoulder rotator or associated muscle impingement injury making
his movement stiff and short thus preventing full and free rotation , is
that accurate ?
Pat Dougherty at IMG emphasizes in his videos that the left hip should bump
forward going into the trophy position, as a kind of brace against the
turned shoulders. This creates a kind of whip (or spring) effect as energy
stored by the coiling of the shoulders is released against the relatively
fixed front hip and leg. The student in the video doesn’t bump out the
front hip, and the shoulders are unwound prematurely.

Great video again. This rotation does add power to the serve, just like the
rotation on a forehand load-up is crucial to a powerful forehand.

Can you talk about front foot ankle safety in serve? My ankle hurts when I
serve for a set & I don’t particularly serve fast & hard.
