But after maybe 50 serves today, I'm quote sore.
This image worries me:
Seems my elbow should be "tucked" tighter and the swing should be more "upward" and driven by my legs.
What do you see?
First of all, wake your pro up from his nap, and tell him to teach you some stuff..Until you get out of the this face up, waiter position, you will never develop a decent serve. If he can't see this, or come up with some solutions, find someone else... This is basic stuff. You need to correct this racquet work before worrying about leg drive. In fact, adding significant GRF with this hand position may put MORE stress on your shoulder.
