If you are trying to flatten your stomach, a great tip is to be sure you work out your invisible abdominal muscles. These are the trasversus abdominis muscles, which are beneath your rectus abdominis. They flatten your waist when you suck in your stomach. In order to work this muscle out, try to pull in your belly button towards your spine. While breathing normally, hold this position for ten seconds.

Power up your heart by doing aerobics. Aerobic exercise, like running, can lower your resting heart rate. This is good because it's a sign that the heart has become more efficient and powerful in pumping blood throughout your body. As your level of fitness increases, your resting heart rate will drop.
