For example, when you are 25 years old, your maximum heartbeat is "220-25= 195" per minute, and when you are 80 years old, your maximum heartbeat is "220-80= 140" per minute.
When your heart rate reaches 60%-90% of the maximum heart rate during exercise, it means that you are burning fat very efficiently. Exercise in this heart rate interval can help you break down fat quickly and lose weight.
When your heart rate is lower than 45% of the maximum heart rate, you can't achieve the effective fat burning effect when you exercise as when you don't exercise.
Extended data:
The fat burning movement needs to meet the following three necessary conditions:
1, the heart rate during exercise should reach the heart rate of moderate and low intensity exercise.
2. Exercise should last more than 20 minutes.
3. Exercise of large muscle groups.
