The power stroke is made with a locked wrist similar to hammering a nail. The forearm does most of the movement while the wrist is immobile. The elbow passes through a horizontal plane as if on an imaginary fence rail during both the forward and backcasts. This motion generates tighter casting loops. It is the most efficient stroke. On the backcast the wrist is also locked. For most short casts use a shorter casting stroke, but for powerful and long casts use a longer casting stroke.
The backcast is made using a hammering or a stabbing motion. This stabbing enhances the strength of the backcast.
The power stroke is a smooth accelerated motion ending in a sudden stop. The acceleration starts slowly and progresses faster until it peaks at the abrupt stop. This stop transfers the energy to the line. Most people are strong forward casters but weak backcasters; similarly, racquet sports players often suffer from the same problem of weak backhand strokes.
