Exercise is very important

Exercising your body is so important, it keeps the body fit. I am the type that sweats a lot, so 5mins of exercise and I am sweating heavily.
I don't really like exercise though, it tiring...but I'm determined to get all these excess weight off so I exercise for about 40mins every day and make sure I loose nothing less than 600calories everyday while I exercise. I do this because I normally have a stressful day, walk up and down so many flights of stairs, walk to class, etc
If you are the type that just sits at home, you need to exercise for more than 40mins and burn more than 600calories.
