Answer :
To determine your estimated maximum heart rate, you can use a simple formula. This formula is widely used and helps estimate the highest number of beats per minute (BPM) your heart can achieve safely when exercising. Here's how it works:
1. Start with the number 220. This is a constant used in the formula.
2. Subtract your age from 220. For example, if you are 30 years old, you would calculate it as follows:
[tex]\[
220 - 30 = 190
\][/tex]
Therefore, for a 30-year-old, the estimated maximum heart rate would be 190 BPM.
Based on the options provided:
- Option A is the formula: [tex]\(220 - \text{your age}\)[/tex].
Options B, C, and D do not correctly follow this method. Therefore, the correct answer is A. 220 - your age.
