First is to not focus too much on using core and kinetic energy. I used to rotate my core/shoulder to fling and propel the racket forward without using too much arm action and it would always deccelerate by the time racket hit the ball. The racket won't release until after hitting. I think the core/shoulder turn is important but the last chain in the kinetic chain is the forearm pronation and instead of a passive pronation, most of the energy should be used to pronate the forearm which drives the racket forward, closes and face and release into the followthrough. It's all about rhs and you need active pronation to give you that high rhs. Don't use the arm and flexion of the forearm to drive the racket. Use active pronation. Keep wrist loose but not extended throughout the swing like a ww. The wrist should be in flexion at end of followthrough. I believe this is how Fed and Nadal do their forehand.
Second is to aim and hit outside of the ball for most shots. This will force you to release into the ball.
Third is to hit ball more to right of you if right handed. This forces you to rotate the body more. Pointing the left arm to the side fence will also force you to do a good unit turn.
Last is to set and be balanced in position before hitting, if time allows for it.
I actually do a little flick before I start pronating the forearm like a whip but not sure if necessary.
This is my way of hitting a fh and there are other ways and techniques may vary.
