kevmoran saidI was never overweight, so maybe this is a different situation. But I used to not workout because... why would I? If you eat relatively healthy and have a somewhat active job, weight and health aren't major issues. The only reason I workout now is to attract men, and that is the only reason all of you workout as well, whether you'll admit it or not.
In short, you work out to be hot. That is not of the utmost importance to most people.
This is incorrect. While eating a healthy diet and being semi-active through your work may keep you at a healthy body weight, it will do little to stimulate muscle growth and an increase in joint strength. In addition, active exercise helps the cardiovascular system maintain its smooth muscle. While a healthy diet will help prevent plaque formation and bloodflow blockages, it will not condition the heart the way exercise will.
Everyone has different reasons for exercising. While most people would not doubt like to look better, some people do it because it is medically necessary. Patients who suffer from osteoarthritis experience much less severe joint pain if they follow a regular swimming routine, for example. Diabetic patients who participate in regular cardio routines experience better glucose control and fewer complications of diabetes (heart problems, neurovascular issues, etc).
Though many guys may not consciously think about it, they are keeping their organs healthy by regularly exercising. If your cardiovascular system suffers, all of your organ systems will. The stimulation of the circulatory system that one gets through regular exercise is not to be undervalued. The heart is a muscle like anything else, and the more easily it can contract, the better one's circulation.
