The benefits of exercising were always well known, but they have truly revealed during the era of the Internet. When people in old days thought of exercising, the image of a man with a bulk body used to strike their mind.
I personally will never want an inflated body with huge muscles. I will rather go for a lean body which can run, cycle, swim, fight, dance and play without showing any sign of stiffness. Apart from these physical benefits, a regular workout can keep us stress-free, disease-free and agile.
