1. It burns calories quickly. A typical CrossFit workout lasts less than 20 minutes, which seems like too short a span to burn a large number of calories. However, studies have recently shown that doing highly intense exercises in short bursts can burn more fat than steady cardio. Men have been shown to burn up to 20 calories per minute.
2. It improves flexibility. By moving the limbs in many different directions instead of a typical repetitive motion, mobility in the joints improves. The well-rounded workouts offered by CrossFit mean improved posture, strength, and balance, not only weight loss.
3. It strengthens the heart. During a CrossFit workout, the heart rate stays highly elevated from start to finish. Individuals participating in these workouts were shown to use the maximum amount of oxygen that can be expelled during exercise. This means that the heart is being worked to its limit, which can mean a lower risk of heart disease.
