Heart rate is a data that must be paid attention when running on a treadmill. This data can directly reflect your exercise state and the effect you can achieve.
1. There is a formula for the optimal heart rate range of aerobic exercise: (220-age)×60%/80%. For example, if you are 20 years old, then the heart beats 120 to 160 times per minute is your best exercise heart rate fluctuation. In other words, if you maintain running in this range, it is most beneficial for fat burning and strengthening of the cardiovascular system.
2. When running on a treadmill, remember to never let your heart rate exceed your maximum heart rate: 220-age. If it is over, please immediately slow down, let the heart rate return to normal rhythm, so as to avoid accidents.
