People come and go in the gym, and the environment is really noisy. When you exercise, you can listen to music with headphones, so as to avoid being disturbed outside, and secondly, you can exercise with the rhythm of music more rhythmically. However, during exercise, the vital capacity is large and the breathing frequency is high. Wearing a mask will lead to poor breathing, which will affect the exercise effect and even backfire. .

I hope I can help you keep fit.
