I regularly get asked how it is possible to gain weight in spite of a regular workout schedule. The person asking is usually on the verge of giving up exercise because he or she is frustrated at having nothing to show for hours spent at the gym. I don’t blame them for feeling that way but quitting is not the answer because exercise has many more benefits besides weight loss. The most common reason for the weight gain is simply that more calories are being consumed than calories burned. Exercise will not help you lose weight if you do not change your eating habits. In fact, there are many aerobic instructors who are overweight in spite of teaching five to seven classes a week. They are fit but they still have excess fat.
