Carrying extra weight around the waist is common for people with pre-diabetes and type 2 diabetes, but it doesn't have to be that way. As a matter of fact, trimming your belly fat will not only help you look and feel better, it can also help reduce your risk of heart attack and stroke. Making your abdominal muscles stronger has another advantage as well: They support the lower back and hold you upright. Continual poor posture puts these muscles to sleep, leaving you with a belly bump as well as an aching back. A good ab workout will tighten your midsection and emphasize other large muscles of your body in a way that increases your metabolism (to burn fat) and improves your posture (to make you look longer and leaner). Use these 15 belly fat-burning exercises to strengthen your abdominal and back muscles.
