To calculate the Maximum Heart Rate (MHR) and Target Heart Rate (THR) for aerobic exercise, you can follow these formulas:

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

2. **Target Heart Rate (THR)**:
The target heart rate zone is typically calculated as a percentage of the maximum heart rate, between 50% and 85%. The formula is as follows:
\[
\text{THR} = (\text{MHR} \times 0.50) \text{ to } (\text{MHR} \times 0.85)
\]

### Example Calculation:
Let's say the age is 30 years.

1. Calculate MHR:
\[
\text{MHR} = 220 - 30 = 190 \text{ beats per minute}
\]

2. Calculate THR:
\[
\text{THR} = (190 \times 0.50) \text{ to } (190 \times 0.85)
\]
\[
\text{THR} = 95 \text{ to } 161.5 \text{ beats per minute}
\]

So, for a 30-year-old:
- Maximum Heart Rate: 190 bpm
- Target Heart Rate Zone: 95 to 161.5 bpm

You can substitute the age in the formula to calculate MHR and THR for any specific age.
