How to improve your tennis serve racket drop

The sixth step of the tennis serve is the racket drop. It's the first part of your forward swing up to the tennis ball. This how to video only focuses on what the upper body is doing. From the trophy pose, the tennis racket drops straight down behind your back like it is pointed at the tennis court. Also, the tossing arm drops down (just let gravity do the work). The racket drop is sometimes called "the scratch-back position" because it looks very similar to trying to scratch your back with the tennis racket.
