Spin or Glide? That Is The Question

"The glide and spin techniques are both means of moving across the shot put circle to get into the power position. No matter what movements are made to get there, getting into this proper position is the key to success for any thrower. An athlete can have picture-perfect technique getting across the circle, but if that fails to get him into the power position, the approach is useless. Proper execution of either method should always result in the thrower being in the proper power position so he can put the full force of his body behind the throw." (Belfiore, 2011)
