Helping out a friend

[joeparr]

I`m no teacher and all I know is what is said here. My friend very talented hits the ball 300 yrds, always in the 70`s. What stops him from being better is a couple of things.He has a slight reversed pivot,pushes alot of driver shots not with irons, and his clubface is closed at the top. He`s muscular and has trouble with flexing his body(turning). Is there any advice on his problem?. I`m trying to get him to go to long island this spring....thanks joe
