Physical activity is essential to keeping you strong and healthy. The less active you are, the more likely you will be to put on weight and put your health at risk. The more you do, the stronger you’ll become. You’re much more likely to feel better and live longer as a result. As well as helping you keep an eye on your waistlines, exercise can also be a great boost for your mood, energy and self-confidence. It’s also a great way to get out and meet new people doing the same thing.
