For squash, fitness is very important. To strengthen up your ankles, one should bike a lot.
For beginners who want to learn squash and become a pro at it, I recommend starting out solo. It not only helps you master the game, but also learn the tactics.
One way to act cheeky on the court is by asking the referee for a break at a crucial time. For example, you have to tie your shoelace. You should take a break for it when your opponent is on a roll and thrashing you. It will piss off your opponent. You can also take these kinds of breaks when you want to get your breath back.
If you are pitted against a player who likes to play really fast – just do the opposite. For example, walk slowly as if you’re walking in a park. This really pisses them off.
Confuse the referee: When you are fighting for a point, ask the referee in a light manner, “Are you sure the ball was up and not down?” This way you don’t only build a healthy relationship with them, but may just get lucky and earn a point too.
