I exercise for 4 hours every day and always sleep in bed at night. What should I do?
I don't know what your fitness content is, but if it's strength exercise, you exercise too long every day. Do not exercise for more than an hour to an hour and a half every day, otherwise it will be counterproductive and harmful to your health. After daily exercise, you should strengthen your rest and restore your strength, and don't stay up late at night.
