Squash
Two players, each with a racquet, take turns to hit a ball onto the walls of the court. The ball has to stay within the designated lines on the walls for the players to score a point.
An Overview of Squash
Squash provides an excellent cardiovascular workout. In one hour of squash, a player may expend approximately 700 to 1000 calories which is significantly more than most other sports and over 70% more than general tennis. The sport also provides a good upper and lower body workout by utilising both the legs to run around the court and the arms/torso to swing the racquet.
The game is played by two players (or four players for doubles) with standard rackets in a four-walled court with a small hollow rubber ball. The scoring system is easy to learn.
