What's up with Interval Training?

Ok, so most of us have a goal of getting lean and losing fat, right? Well, we're doing that in bootcamp by using efficient exercises--full-body exercises that allow you to train several muscle groups at once. Obviously the more muscles used per exercise the better. By doing pushups, for example, we can train our chest, shoulders, and abs all at once. Lifting moderately heavy weights for a lower number of repetitions will help gain muscle (not bulk you up) at the same time as you lose body fat, and it will also help you burn a lot more calories during your workout and after.
To lose fat, you have to choose the right total body exercises, exercise at the right intensity and perform shorter bouts of metabolism-boosting interval training to get results. If you do this, you'll not only reach your goals faster, but you'll cut down on your workout time.
