      Many fat loss concepts are based on how many minutes of continuous aerobic exercise have the best fat loss effect. The aerobic time is guaranteed to be 45-60MIN for the best effect. Many people here have a question: Can you lose fat by exercising within 30 minutes? Today I will explain this issue to you in detail.

      1. The first thing to make clear is:

      It’s not that fat will start to be consumed only after exercising for more than 30 minutes. In fact, fat will start to be consumed slowly when exercise begins, and it will only reach the peak at about 30 minutes. But if you only exercise for less than 30 minutes, the fat consumption during exercise can be almost ignored. Therefore, the conclusion drawn is: aerobic exercise within 30 minutes does not mean that fat cannot be consumed, it is just that the consumption is too little and the effect of fat loss cannot be achieved at all.

      2. Secondly, is it true that only long-term aerobic exercise can lead to weight loss?

      The answer is no, long-term aerobic exercise is only the simplest and most practical way. High-intensity intermittent exercise can burn fat better and has a better effect on fat loss.

      In simple terms : High-intensity interval training and anaerobic training can improve metabolism. Improve the body's ability to consume calories and fat over a period of time. In the long run, fat loss and weight loss are more effective.

      3. What kind of weight loss exercise is the most effective and scientific?

      It is undoubtedly very stupid to only rely on diet and a lot of aerobics to lose weight, and it is also very easy to encounter a bottleneck period. The simplest and most crude method is aerobic and anaerobic interval training. Training like HIIT is a good way to lose fat.

      Theoretically speaking, anaerobic energy promotes metabolism, while aerobic energy stresses the body, increases appetite, and promotes fat storage. A combination of the two is the most effective way to lose fat.

      In general, fat loss does not mean mindless aerobic training. In addition, anaerobic training can not only improve the efficiency of fat loss, but also help shape the body. After cutting off the fat, you will find that you have good muscles.
