Huge power can be transferred to thrown or struck objects by using proper body rotation. Here are some examples from other sports apart from golf shown in slow motion.
Lumberjacks in action— Notice Balance, rotation, arm leverage, for power and accuracy.
The latest craze is disk golf, unbelievably some of these players can throw golf disks up to 800 feet! (well over 200 m)
If you watch the video, the power source appears to originate from body rotation. As most of these players are throwing the disc right handed, the body rotation is similar a left handed golf swing. For a right handed golfer, practise the throwing action with the disc held in the left hand.
Use the same body rotation coupled with a hinged right elbow action on the downswing, then expect to hit longer drives.
These super slow motion videos of Dustin Johnson demonstrate body rotation to the extreme. I doubt our GreyPower bodies still have the ability to constantly move this way when swinging, the senior body is unlikely to be flexible enough or have the range of movement and strength required. However, these videos do show tremendous power can flow to the club head from using the leverage and body rotation created in thoroughbred athlete’s swing.
