An exercise regime will only bear the kind of results you are looking for if you accompany it with the right diet. This is known as a “holistic” approach, where you view every part of your routine in a critical fashion and look to see what you can do to make it the best it can be in every way. If you are studying for an exam, on which questions will be asked on a range of topics, it is all well and good studying heavily on one of those topics to the point where you could answer every question that could be thrown at you on that topic – but if you ignore all the others in doing so, you’ll end up failing.
So it is with body building. You can be the most committed trainer that there ever has been, and you will effect positive results in some respects. But if you are just eating fries and burgers all of the time, you will not be giving your body some of its most vital nutrients. You will get tired more quickly, train less effectively, and sustain injuries. For this reason it is worth taking a realistic view on diet – cut out the ice cream sundaes for a time, drop the greasy burgers and lay off the beer, too. Alcohol does horrible things to muscle recovery.
Of course, you can work scheduled breaks into your regime – in fact it is probably advisable at the beginning – during which you can treat yourself. Just remember the end goal when you have to get back to training.
