The why is the latissimus dorsi muscle. That is the swimmer wings that you see also on gymnasts. This muscle is the largest back muscle and is responsible for the twisting motion of your torso. Yea it's important for the swing. If you could see a picture of the muscle you would see that it attaches to the front of your upper arm, to much of your thorasic vertebrae and then to your hip. In fact the lat is the primary stabilizer for your hip on the back; your abdominal muscles are the primary stabilizers for the front.
Even if you don't have wings, if you have strength in your lats you have torso power. You can't expect that little ole tricep to power that little white ball as far as you want so get that big back goin'
