With winter almost upon us, our repertoire of exercises shrivels up to a few choices. In North India winter is often accompanied with fog. This makes cycling or even driving to the gym a dangerous expedition. However, hope is still at hand. There is one simple exercise that will help you maintain your fitness around the year, especially though the lean winter months. This exercise does not require any training equipment, systems, and fad diets which is mostly the result of marketing rather than a genuine effort to reach higher levels of fitness and well-being.
