Fitness Myth: #4

Myth 4: Heart rate is the best measure of a hard workout

CrossFit is a data driven program. We love to record weights, rounds, reps, meters, calories and times. While these measures are good for keeping “Score” what they really do is help you determine how intense your workout was. Intensity is what drives results in a fitness program.

In other fitness pursuits, particularly endurance sports, people often use heart rate as a measure of intensity. While heart rate does give you an idea of how hard you are working, there are also some problems with relying on it as your primary measure. Many factors will affect your heart rate: hydration, stress levels, recovery status, and mode of exercise, to name a few. Your resting heart rate can fluctuate by as much as 10 beats per minute based on these factors. That doesn’t mean you are resting more “intensely” on a day your heart rate is higher. Additionally, just thinking about a hard workout or a stressful situation can increase your heart rate without doing a thing for your fitness.

These are all examples of why we don’t rely on heart rate as a true measure of intensity. We consider heart rate a correlate of intensity. If I know that your “Fran” PR was 5:00 and today you do “Fran” in 4:30, regardless of what your heart rate was, I know that your workout was more intense. I don’t need a fancy heart rate monitor to tell me that. Does that mean that heart rate data is worthless? No, it’s just not a be all, end all data point and definitely not the best measure of intensity.
