How do you accelerate an "axe handle"?

I think if a Hitter follows Kelley's advice and employs the advantage that a Hitter may end his backstroke when the right elbow becomes bent, then a Hitter can grip it tight and hit as hard as he can with his right arm while keeping his body steady. Shorten the stroke, still the body, and deliver Tommy Armour's (bent back) right handed smash!

I've been finding(for me, anyway) that keeping the body still is paramount in my hit. Looks like yoga(to loosen up the back and neck) and balance ball swings are the order for over the winter...
