Dieters: Music To Your Ears
Faster music can better prepare you for an intense workout as well - it increases heart rate and respiration. Look for songs that are consistently fast and rhythmic, with a driving beat. Dance mixes of popular songs work well.
Avoid songs that vary too much in beats, and those that are more free form - these are best saved for slower, less intense workouts, stretching and cooldowns. When you are ready to cool down, soft, calming music can help soothe nervousness and anxiety. So whether it's Bach or Beck, find something you love that's well-suited for your kind of workout.
