Music helps us exercise—but why does it have this effect? Experts say there are two main reasons.
The is simple: music takes our attention away. When we listen to a song we like, our brains focus on the music. For example, After we exercise 20 minutes, our body might be tired. But we may not feel this immediately we are listening to music. So we can exercise a little longer.
Music also makes us want to move. When we hear dance music, for example, we naturally start to move to the beat. A positive song also puts us in a good mood, so we feel much .This gives us energy and helps us exercise longer. Music with a quick and continuing beat is good for exercising. "But the music shouldn't be too fast, " Dr. Costas, a famous sports expert. In general, songs in the range of 120-140 beats per minute (BPM) are the best.
