It is better to exercise at night than in the morning. I have read this magazine before (it is true). And the air quality in the morning is the worst in a day (the best air should be at noon)
But it is not good to exercise too late at night (1 bedtime is too close to sleep time). After exercise, all the functions of the brain and body are in a state of excitement, which is not conducive to rest. Didn't you say that you should have a good rest after exercise to slow down your body?
So it is recommended not to do strenuous exercise within 2 hours before going to bed (just like drinking water within 2 hours before going to bed).
