Increasing muscle mass is an effective way to burn calories. Muscle tissue burns more calories than fat. Ten pounds of muscle burn approximately 50 calories a day while the body is at rest, while 10 pounds of fat burn about 20 calories daily.
Strength training is a great way to increase muscle mass and, ultimately, burn more calories. Strength training is especially important as people age due to decreasing muscle mass, joint pain and slowing metabolism. The largest muscle groups that burn the most calories include the chest, thighs, abdomen and arms. In addition to strength training, regular aerobic exercise, such as taking brisk walks, is another highly effective way to burn calories.
