First, the heart rate problem. Generally speaking, aerobic weight loss, the heart rate should be between 120- 150, too low is ineffective, too high, the heart burden increases, and it is not desirable. But that doesn't mean you have to lower your heart rate to be effective. In addition, everyone's calm heart rate is also different, which also leads to the different exercise heart rate.

Second, the number and amount of exercise, 3-4 times a month, is definitely not enough. If you want to lose weight, you usually have to exercise more than 2-3 times a week to have obvious effects.

Aerobic weight loss, generally speaking, it takes 20-25 minutes to consume sugar in the body, and then it will consume fat, so this time is called the critical point, so it is better to exercise for about 40 minutes at a time, and you can slowly run to reach the heart rate 12- 150, which can get more continuous exercise time and is conducive to weight loss.
