About RPE Calculator: Understanding Rate of Perceived Exertion

What is RPE?

The importance of exercise for maintaining good health is well-known. Beyond just exercising, it’s essential to monitor the intensity of your workouts. One effective way to do this is by using the Rate of Perceived Exertion (RPE) scale, also known as the Borg Rating of Perceived Exertion scale. This method helps gauge the intensity of your physical activities.

Intensity Levels Defined by RPE:

  • Low Intensity (RPE 1 to 3): Breathing is easy, talking is uninterrupted, and you feel comfortable.
  • Moderate Intensity (RPE 4 to 6): Breathing becomes heavier, speaking is in short phrases, but you remain comfortable.
  • High Intensity (RPE 7 to 9): You are pushed out of your comfort zone, breathing is heavy, and speaking is difficult.
  • Maximum Effort (RPE 10): Speaking is impossible, breathing is very difficult, and you are pushing beyond your physical limits.

Understanding Perceived Exertion:

Perceived exertion is measured by the physical sensations experienced during exercise, such as increased heart rate, deeper and quicker breathing, sweating, and muscle fatigue. These indicators, though subjective, can help assess your workout intensity even without technical equipment.

Calculating Your RPE:

To determine your RPE, select a number from 1 to 10 based on how tired your muscles feel, how fast your heart is beating, and how your breathing has changed. The higher the number, the more intense the workout. An RPE of 1 signifies minimal exertion, while an RPE of 10 represents maximal effort.

If you use a heart rate monitor or want to manually check your pulse, here are steps to follow:

  1. Find your pulse on the inside of your wrist, near your thumb.
  2. Use the tips of your first two fingers (not your thumb) to press lightly over the artery.
  3. Count your pulse for 30 seconds and multiply by two to find your beats per minute.

Benefits of Using RPE:

The RPE scale offers a straightforward way to ensure you meet the recommended 150 minutes of moderate or 75 minutes of vigorous exercise per week. It focuses on how you feel rather than specific metrics like heart rate or pace, allowing you to adjust your workout intensity based on your body’s feedback.

The Borg Scale in RPE:

Developed in the 1960s by Swedish scientist Gunnar Borg, the Borg scale ranges from 6 (minimal effort) to 20 (maximum effort). Each point corresponds to the level of exertion felt, influenced by signs like an increased heart rate, accelerated breathing, muscle fatigue, and sweating. It’s important to consider overall feelings rather than focusing on a single indicator.

Differences Between the Borg RPE Scale and the 1-10 RPE Scale:

Both scales effectively measure workout intensity based on the exerciser’s feelings. The choice between them may depend on which seems simpler or more intuitive. The Borg scale offers a rough correlation between the exertion level (multiplied by 10) and actual heart rate, which can be especially useful for aerobic activities. Conversely, the 1-10 scale is valuable for strength training, indicating how many reps a person might still perform with good form.
