People who think that this game is easy are just plain silly. An hour of intense exercise is difficult as it is, but when you have to be looking at everything that goes on on the court on top of using every muscle in your body and never standing still, it can be hard to keep up your usual standard. You're always moving and sometimes it feels like no matter where you go, you're running into a jungle of arms and legs so avoiding everyone's limbs is also half of the challenge.
