I doubt any exercise can beat running in improving our health in both mind and body. Twenty minutes of running at least three times a week can make a huge difference in our well being. Twenty minutes of running is more effective than even six hours of walking. Running makes us feel much better and makes us sharper with better functioning of our brain. It is also very good for our skin, after several months of regular running, we will see the difference, it will make the skin glowing and radiant without using the artificial make up. Of course, it should be with healthy eating too, by avoiding the processed foods and just eating fresh and home made foods.
