One of them firmly believes that exercise must last for more than 30 minutes, otherwise you can't burn fat.
The other one ran two or three laps in the playground, happily waiting to lose weight.
After all, how long does exercise take to lose weight?
Scientists conducted a study. After the subject implanted the detector in his arm, his blood sugar began to consume in the first minute after exercise. After exercise 10 minutes, the blood flow of adipose tissue increased, indicating that fat began to burn, and the blood flow of adipose tissue reached its peak at 30 minutes of exercise. At this time, even if the exercise is stopped, the highest blood flow concentration of adipose tissue can still be maintained for 6 hours, and even if the exercise time exceeds 30 minutes, the exercise fat can only be burned for 6 hours.
Judging from the direct heat consumption of exercise, under the condition of equal exercise intensity, if you continue to exercise for 30 minutes, the heat consumption will be the same if two or three exercises add up to 30 minutes. But if your goal is to lose weight, you'd better pay attention. I mean the best, and it doesn't have to take 30 minutes. Fat can burn for 6 hours.
