Question

how do you determine your target heart rate?
a to determine your maximum heart rate, subtract your age from 120, then multiply this number by 0.60 for the low end of your target heart range and by 0.90 for the higher range
b to determine your maximum heart rate, subtract your age from 220, then multiply this number by 0.25 for the low end of your target heart range and by 0.90 for the higher range
c to determine your maximum heart rate, subtract your age from 2020, then multiply this number by 0.50 for the low end of your target heart range and by 1 for the higher range
d to determine your maximum heart rate, subtract your age from 2020, then multiply this number by 0.60 for the low end of yout target heart range and by 0.90 for the higher range

Answer 1

To determine your target heart rate, the most commonly used formula is option **B**:

**B**: To determine your maximum heart rate, subtract your age from 220, then multiply this number by 0.50 (or 0.60 typically) for the low end of your target heart rate range and by 0.85 (or 0.90) for the higher end.

Here's the general process:

1. **Calculate Maximum Heart Rate (MHR):**
\[
\text{MHR} = 220 - \text{age}
\]

2. **Determine Target Heart Rate Range:**
- For the lower end of the range:
\[
\text{Lower end} = \text{MHR} \times 0.50 \text{ (or 0.60)}
\]
- For the upper end of the range:
\[
\text{Upper end} = \text{MHR} \times 0.85 \text{ (or 0.90)}
\]

This will give you a target heart rate range that you can aim for during exercise for optimal cardiovascular benefits.
