ОА.
40%-50%
OB
50%-70%
Ос.
70%-85%
OD
85%-1009

D. 85% - 100%

Explanation:

Our heart rate depends on what we're doing. For example, it will be the lowest when we're sleeping or resting, and the highest when we're performing high-intensity activities. The maximum heart rate ranges from 85% to 100%.

However, you shouldn't push yourself too hard. It's possible to reach the maximum without any consequences as long as you don't suffer from any cardiovascular issues, but you may end up with a musculoskeletal injury. If you go above 85% of your heart rate, you could get sore joints and muscles.

so i really think that most of the health care industry be doing more bad than good.
