If Joe takes a 6-second heart rate count on his client and notes 8 beats, what would his client's heart rate be?

To calculate the heart rate based on a 6-second count of beats, you multiply the number of beats counted by 10, as there are 60 seconds in a minute. In this case, Joe counted 8 beats in 6 seconds.

The formula used for this calculation is:

Heart Rate (beats per minute) = (Number of beats in 6 seconds) × (10).

Applying this to Joe's count:

Heart Rate = 8 beats × 10 = 80 beats per minute.

This calculation accurately reflects the client's heart rate, confirming that the correct answer is 80 beats per minute. Understanding this method is crucial for fitness professionals to accurately assess and monitor their clients' cardiovascular health.
