I don't think it's so much strength, it's just getting used to understanding the feeling and motion of how the club needs to be swung. I've seen plenty of female golfers struggle to swing the club, and then they get a little bit of good instruction and/or start to get better as they practice more and they have no problems swinging the club. To me, I don't *believe* they are realy more powerful. I don't believe they will get up on the bench press and move more weight. It's just getting used to it. Sort of like learning how to play guitar. At first you fumble around, but after awhile you start to get the hang of it. Doesn't mean you have more dexterity, IMO. Overall, I think strength in golf is vastly overrated.
