Under what circumstances does strength take precedence?
If you want to exercise your muscles, or if you are a professional athlete, you need to concentrate on exercising your muscles, so you'd better do aerobic exercise the next day.
Aerobic exercise will deplete your body's energy reserves. If you choose to do aerobic exercise at this time, it may affect your strength training performance. If you can't challenge the weight and quantity of the training group you want, it will also affect your mentality to some extent.
Please note that the point here is not to make you think about the first 5 minutes of cardiopulmonary training. Just say you don't want to run 10 km and do squats!
When is aerobic priority?
If you have enough time, you can arrange your own aerobic training day. Unfortunately, most people don't have time to do this.
If you are going to make a breakthrough in endurance training or run a marathon, then it is definitely right to focus on aerobics. Of course, you should also insert some strength training to help yourself avoid injury.
Strength training is different from aerobic training, but because time is limited, you must put them together in many cases. Some people say that aerobic training is followed by exercise, while others say that it is the right way to exercise strength first, but you have never come to a clear conclusion. So the answer to this question is ultimately everyone's fitness goals and fitness time, because everyone is different, which leads to different views.
