What do you normally do, when you brush your teeth?

If you want to work the deep core muscles in your abdomen which protect your back, you can stand on one leg. Tim Hutchful- chiropractic and ergonomic consultant in Leicester says that lots of people never work these deep muscles, and this is the perfect opportunity to give them a short but effective workout. The other idea how you can do it, is to standing on the opposite leg for one minute during the brushing, then reverse. The more variation you put in, the better result you would have.
