In those exorcism horror movies, the priest has to have consent from the possessed individual to begin the exorcism. That's because the exorcism will not work if the individual is unwilling to be rid of the demons. The individual cannot give in nor give up hope. They must be strong and faithful.
I'm saying this to hopefully give you another perspective to fitness and exercise. It's not just about obesity, but also the habits and addictions we give in to with obesity being the likely result. Too much eating and not enough exercise to burn the calories. Or exercising the right way but not eating the right foods, thinking the exercise would burn off the calories, or thinking the exercise balances out the junk food we consume. It's not that easy. You have to be willing to dedicate yourself to being healthy, without giving up. Exercise and a nutritional diet can help get you there! And need I remind you about supplements?
If you're reading this with a donut in your mouth, asking yourself, "I should start working out. But where do I even begin?", you first have to be willing to dedicate yourself to getting healthy. So the best place to start is by throwing the rest of that donut away and reading on!
If you're reading this, and if time permits, I suggest dropping everything and picking up some training equipment. A set of dumbbells and a bench is a basic, but good way to start you off. You can check out vids from Bodybuilding.com for a directory of exercises for every muscle group, most of which can be done at home. Give it about a week or two, and when you start to feel stronger, then you should sign up to a gym. Training at home will boost your self esteem and, of course, build some muscle and strength before you start to hit the gym. If you do decide to start at home, I would suggest taking alot of antioxidants, because of the air you breathe in your home may not be as clean as the air outside, or in the gym. Green tea would work best for you here.
Don't let your gut be your inner demon and tell you that it's too late, that exercise won't work because you're just too obese, or too busy. And don't give in to it by telling yourself that you're happy with being overweight. If you think you're happy now, just try working out for a couple months - you'll be ecstatic then!
