Definition: A drill is simply a training routine used by two players, such as forehand topspin to forehand block, where one player is working on one part of his game (his forehand topspin), and the other player is working on another aspect of his game (his forehand block). In most cases, one player will be doing a more complex pattern than the other (i.e. the player hitting the forehand topspin might be hitting the ball from two different places).
The player who is doing the simpler part of the routine (in this case, the person blocking the ball) is called the feeder.
