Perpetual Motion

An incredibly tiring drill for the sport of water polo, in which at no time does a player stop moving in the water (hence the name: perpetual motion). Perpetual Motion, though tiring, can be quite fun if there are a large amount of players. However, without enough people, the players tend to be too exhausted to enjoy themselves, even if getting an extreme workout. At first, Perpetual Motion, also called "Perpet." (per-petch), is a confusing drill to learn, with players swimming all around to different parts of the pool and polo balls being thrown at both nets. Once the drill is learned, it is easy enough to follow though.

Person: Hey! Want to hang out?
Water Polo Player: I'm too tired, I'm gonna go sleep. We did perpetual motion for half of polo practice today.
