HOW TO: There are the two effective methods for calculating the level intensity during exercise.
RPE Scale
The Rate of Perceived Exertion can be used to measure how hard an individual is working. The RPE scale ranges from 0-10, corresponding to the intensity of exercise.
Light activity level: ranges between 2-3.
Moderate activity level: ranges between 4-6.
Vigorous intensity level: ranges between 7-8.
Talk Test
The Talk Test is the simplest and most accurate way to determine the intensity of how hard your heart is working.
Beginner activity level: You're able to exercise while engaging in conversation.
Moderate activity level: You're able to talk, but not sing, during exercise.
Vigorous activity level: You're unable to talk during exercise without pausing for a breath.
