3. Synchronisation with the Music Makes for More Efficient Workouts

Music may or may not synchronise with your workout. The advantage of choosing music that does is that it acts as a "cheerleader" while you exercise. Studies suggest that this makes exercise more effective, allowing you to use less oxygen and therefore making cardio more efficient. This has proven to be an effective technique for professional athletes, and although you won't reach their levels of fitness, you can certainly apply the same technique to benefit your own exercise sessions.
