Pushups

The first exercise you ever did may be the best you'll ever do: The classic pushup trains your chest, shoulders, triceps, abdominals, lower back, and glutes. Why does it burn fat? The more muscles you work, the more muscle you build. And muscles burn calories.

How to do it: Assume the classic pushup position: legs straight, hands beneath your shoulders. Now brace your core. Keeping your body rigid, lower yourself until your chest touches the floor. Then push back up until your arms are extended.
