Blast your biggest muscles. A study in the American Journal of Clinical Nutrition showed that women who pumped iron upped their burn-off by 300 calories a day. To kill off more calories each aerobic workout, increase the speed or intensity. For example, if you run on a treadmill, up the speed or raise the incline. Adding hills ups the count another 50 calories.
Music is a great motivator.
Studies show that exercisers who tune in to music work out 25 percent longer. Trek to the toilet. Instead of going to the closest bathroom at work, take the stairs to another floor. Every minute you climb kills seven calories. This may be a challenge at times, but you reap the benefits.
