i just added the full body turn into my swing(use to swing with arms alot), and now im taking divots in front of the ball more often which is great.
One thing is though, this swing is harder for me, takes for out of me, just wondering if with more flexibility the swing will feel for natural.

Also, what stretches would you recommend for me to help with this

Sit down with good upright posture. Turn your shoulders as if making your backswing, until you feel your muscles stretch. Hold for 20 seconds. Repeat several times per day. For good measure, do the same in the follow-through direction. If you remember to do this with some regularity, you can gain flexibility without hardly any effort.

gdel, practice by swinging two clubs held together. The added weight will help stretch those muscle's. I have seen Miguel Angel Jimenez swing 3 clubs held together as part of warm up but i would'nt recommend that just yet.
