If you would like to get 'fit', perhaps the best course of action is to go down to the local gym and book yourself in for a fitness assessment and have them put you on a fitness program which is tailored specifically to the needs of your sport. If you are seriously out of shape, the first stage is to lay off the beef burgers and then see your doctor to make sure your heart, lungs and other internals are up to the job.

You may do yourself a BIG favour at this point by being brutally honest with yourself. Better still, get a friend/partner to give you an honest opinion of your health state. Research has shown that most of us regularly over-estimate how fit we are and how much real physical activity we do.
