Also you do realize that the Lock and Roll guy is a pretty accomplished player and coach? I've personally found his videos to be very helpful.

Just go grab a tennis racquet and a ball, go out to your favorite wall, and hit a few. Serves, ground strokes and overheads all work on the principle that larger muscles groups unload energy into whipping the racquet into the ball. Actually most sports that involve throwing and hitting things use this concept. Just throw a ball - same idea. Your legs and core whip your arm around to throw.
I'm not here to prove anything to anyone. I say only that for years I left the control of my forehand to the trunk and legs ..and I'm still waiting yet to see a decent ball come out from my strings (a bit of spin and a bit of speed.. don't pretend so much).

Only when I moved my attention to the speed of the arm in the forward swing the level of my forehand has changed, that doesn't mean i don't use legs and trunk .. only i don't think at them, I know my lower body is loaded and that's all, so I cannot do other then to conclude that the arm is crucial in the production of ball speed ... crucial.. and the matter the arm go fast.. are we! Kinetic chain does anything by itself. The lines attached in the monkey drum don't impact a mass .. we need to do it, that changes everything .. dragging the arm like a monkey drum is not enough and the nice R&L guy would spend some words in why and what he does with his arm too.. because, by me, it isn't secondary.

But mine is only very modest opinion of a tennis fan, so take it for what it is.
