The Throwing Stick

[Scythe13]

Stand with your legs planted and your upper body relaxed. Then turn your hip. If your upper body is relaxed enough you'll notice your arms rotate in the direction of your hips, but a second or so later. The thing is, the ends of your arms will have a greater speed than your lower body. This is because they will travel the same speed, but on the outside of a circle. Just like how the inside of a CD rotates at a slower speed than the outside, even though they both do the same number of RPM's.

The thrower can then use the same principle to transfer the greater speed to their projectile. Also, the legs and hips are much stronger than the chest and arms, and so the transfer of energy, if performed correctly, can be huge! At 14 years old, I was able to throw a 1.5kg discus over 40 meters, and the same with a 4kg hammer. I was a fat kid, which made my legs strong (carrying around that weight), but thanks to my coach being so particular about technique, I learned to transfer energy pretty well. His meticulous manner also made picking up boxing and the basics of Wing Chun very simple.
