Aerobic training is best done on an empty stomach in the morning and immediately after strength training.
Because there is a lot of energy in the human body, only when the energy consumption is almost the same, reducing fat is the best effect.
If you do aerobic exercise first, you will consume energy instead of fat for a long time, so you should consume energy first and then fat.
Usually get up on an empty stomach in the morning, and the energy in the body is not enough, so the effect of reducing fat is very good.
But after strength training, energy consumption is more thorough, so do strength training first, and then do aerobic training.
Of course, you should do 5 to 10 minutes of aerobic warm-up before strength training.
