Sure, you have your personal preferences. But whatever musical style you favor, you might want to check the beats per minute (bpm). You can look for apps that can help you determine the bpm. Choose songs that mirror your heart rate, depending on the level of exercise.
As you pick up the pace to a moderately intense level, songs within the 120-140 bpm range are ideal. Songs over 140 bpm are unlikely to improve workouts.
Don’t Rely on Music
You run the risk of being too dependent on using music as fuel for motivation. From a psychological point of view it’s all about conditioning — you are conditioning yourself to exercise with music and expect it to be present, so when it is suddenly removed you can expect a poor performance.
That’s why you should cast MP3s aside once in a while to get used to performing without music. For every two workouts with music, do one workout without music.
Watch the Volume
Crank up the volume on a hard workout, and your hearing may suffer.
High-intensity music coupled with high-intensity exercise can cause temporary hearing loss. During exercise, blood from the inner ear rushes toward the working muscles, making you more susceptible to hearing damage.
Because hearing loss is gradual and may take several years to appear, it’s important to take proper precautions before it’s too late. If you use headphones, follow the “80 for 90 rule.” This means that it is safe to listen to music on a portable device, such as an iPod, at 80% of the maximum level for no more than 90 minutes a day. Any more than that and you risk overworking the ear.
