Exercise can help reduce the likelihood of you acquiring a disease because it bolsters your immune system. It allows your body to maintain homeostasis, that's its normal state of being. All systems go; everything's working as it should. The way I perceive it, when you're in really good shape, you have super homeostasis. It's not just that all systems are go, it's that everything is at a very high level of functionality. Your body's better able to respond, your blood chemistry is correct, and you also have the physical ability to defend yourself against a foreign invader, whatever that may be. If your body is compromised because it's not physically strong, and you get some sort of disease process, it may get the better of you. This may be simply down to whether you have had to take medicines, if the disease has given you a fever or it's dehydrated your body, or if you've lost muscle mass when you didn't have much to begin with; if so, you're really at a deficit. If your body's incredibly strong and you do get ill, you're better able to fight it off, win, and bounce back quickly as well.
