I really hate snakes, but this name makes sense so I will leave it as-is. The concept is simple and can be used for all kinds of shot production. We used it to work on split steps and volleys.
Coach is feeding from service line. Players are lined up across net. One at a time they move up to starting spot (about halfway between service line and net) and split step. Coach feeds out wide to their forehand, where they move to hit a volley, then immediately run to back of line.
If this is working properly, the players are snaking through at a pretty good clip, so it is not as heinous as some of the other dreaded line drills.
