what is MHR
A
maximum heart rate
B
minimum heart rate
C
medium heart rate
D
all of the above
Explanation: 

Detailed explanation-1: -You can estimate your maximum heart rate based on your age. To estimate your maximum age-related heart rate, subtract your age from 220. For example, for a 50-year-old person, the estimated maximum age-related heart rate would be calculated as 220 – 50 years = 170 beats per minute (bpm).

Detailed explanation-2: -For most of us (adults), between 60 and 100 beats per minute (bpm) is normal. The rate can be affected by factors like stress, anxiety, hormones, medication, and how physically active you are. An athlete or more active person may have a resting heart rate as low as 40 beats per minute.

Detailed explanation-3: -The traditional method, also known as HRmax, is a simple way of gauging your maximum heart rate. Start by subtracting your age from 220. Then, use the result to calculate your range. For example, if you’re 50 years old, the calculation would be: 220-50 = 170 (HRmax).

Detailed explanation-4: -Fitness Training Zone 2 (60 – 70% of MHR) – This is the zone where the heart begins to benefit. The heart will be over worked and therefore grow back bigger and stronger becoming more efficient and improving the hearts ability to pump blood and improve the muscle cells ability to utilize oxygen.
