Question

question 4 of 5
how are the lower and upper limits of your target heart rate range defined?
a. ranging from 50% to 90% of your maximum heart rate.
b. taking a pulse in the first and last ten minutes of a workout.
c. subtracting your age from your maximum heart rate.
d. ranging from 30% to 70% of your maximum heart rate.

Explanation:

The target - heart - rate range is commonly defined as ranging from 50% to 90% of an individual's maximum heart rate. This range helps in achieving an effective and safe workout. Option B is about taking a pulse at specific times during a workout, not defining the range. Option C is a formula for estimating maximum heart rate, not the range. Option D has an incorrect percentage range for the typical target - heart - rate range.

Answer:

A. Ranging from 50% to 90% of your maximum heart rate.
