What is RPE in Lifting? Unraveling the Secret to Smarter Workouts

If you’ve ever been to a gym or worked with a personal trainer, you may have heard the term “RPE” thrown around by other lifters and trainers. RPE stands for “Rate of Perceived Exertion,” a subjective measure of how hard you feel when working during a workout.

While it may seem vague or arbitrary, RPE can be a valuable tool for optimizing your workouts and achieving your fitness goals.  From understanding the RPE scale and its different levels to incorporating RPE into your workout routine, you can gauge the intensity of your workouts.

Keeping track of your RPE ratings in a workout journal will help you make informed decisions about when to increase the weight, add volume, or even take a step back to recover.

The RPE Scale and Its Origin

The RPE (Rating of Perceived Exertion) scale is a subjective way to measure and communicate the level of difficulty you experience during a workout, specifically when lifting weights.

RPE is designed to indicate how hard you’re working based on your bodily sensations and personal perception of effort. The RPE scale has its roots in the Borg Scale, developed by Swedish professor Gunnar Borg.

Gunnar Borg and the Borg Scale

Gunnar Borg, a Swedish psychologist and exercise physiologist, developed the Borg Rating of Perceived Exertion (RPE) scale in the early 1960s. This scale was initially created for use in cardiovascular exercises and ranged from six (no exertion at all) to twenty (maximal exertion).

Borg designed this scale based on the idea that there is a linear relationship between an individual’s perceived effort and heart rate during physical activity.

Modified RPE Scale

As weightlifting gained popularity, the need arose for a more specific scale to gauge the intensity of resistance exercises, leading to the development of the modified RPE scale.

The modified RPE scale ranges from one to ten, where one represents minimal effort, and ten signifies the maximum effort you can exert.

To help you better understand the intensity associated with each level, here’s a brief breakdown:

  • 1-2: Straightforward warm-up sets
  • 3-4: Moderate effort, a comfortable pace
  • 5-6: Challenging but manageable
  • 7-8: Hard, pushing your limits
  • 9: Very hard, barely able to complete the set
  • 10: Maximum effort, failure to complete the set or last repetition

Utilizing the modified RPE scale in your training can better monitor your progress, adjust your workouts, and optimize your overall lifting experience.

Understanding RPE in Lifting

Rate of Perceived Exertion is a powerful tool that can help you gauge the intensity of your weightlifting sessions. It allows you to quantify your effort to optimize your strength training and load management.

In essence, RPE is your internal defense mechanism, helping you to prevent overexertion and possible injury while progressively increasing your workout intensity.

Subjectivity and Intensity

Unlike more objective measures, such as sets, reps, and weight, RPE is a subjective method considering personal factors.

By understanding your body’s perceived exertion, you can tailor your training to maintain a balance between pushing yourself and avoiding overtraining.


This helpful approach allows you to fine-tune your strength training based on your current capabilities and energy levels. RPE is especially valuable when working around injuries, as it can help you manage intensity without aggravating the affected area.

RPE and Load Management

Effectively managing the training load is crucial for growth and progress in any lifting program. Implementing RPE into your training regimen helps you make informed decisions about adjustments to intensity and volume based on your body’s feedback.

Here are some critical connections between RPE and load management:

  • Individualization: RPE acknowledges the unique differences among individuals and their varying fitness or experience levels.
  • Adaptation: RPE allows for adjustments in line with your progressive increase in strength, helping your body to adapt and grow more efficiently.
  • Autoregulation: RPE allows you to customize your daily training plan based on factors like fatigue, stress, and injury, maximizing productivity and recovery.

Integrating RPE into your lifting routine can lead to more sustainable and effective workouts that align with your personal goals and limitations. Remember, learning to listen to your body allows for better communication with your unique needs and, ultimately, more successful performance.

Application of RPE in Strength Training

RPE, or Rate of Perceived Exertion, is a valuable tool in strength training that allows you to gauge the intensity of your workouts based on your perception of effort. Using RPE, you can manage fatigue, tailor your exercises, and optimize your progress in various strength training disciplines.

In powerlifting and weightlifting, maximizing your performance in the squat, bench press, deadlift or snatch, and clean and jerk is crucial.

Incorporating RPE into your training ensures you work with appropriate intensities, allowing for effective stress management and skill development.

For example, instead of using a fixed percentage of your 1RM, you can use RPE to account for daily fluctuations in your strength levels. This can lead to more accurate and individualized programming while reducing the risk of injury.

Bodybuilding and Hypertrophy

While powerlifters and weightlifters typically focus on technical precision and strength, bodybuilding and hypertrophy training prioritize muscle growth. RPE can be beneficial in creating an optimal stimulus for muscle gains.

Keeping track of RPE during your workouts enables you to target specific rep ranges and effectively manage fatigue. This translates to better quality sets and improved muscular endurance.

Additionally, RPE can aid in gauging the effectiveness of various exercises, allowing you to adjust and select the most beneficial movements for your specific goals.

RPE and Recovery in Training

RPE, or Rate of Perceived Exertion, is a valuable tool for gauging your level of effort during weightlifting. Understanding RPE will help you refine your training and improve recovery. Below, we’ll explore how RPE connects with muscle fatigue, pain, and injury prevention.

Muscle Fatigue and Pain

When you push yourself too hard, your body can experience physical discomfort and reduced performance. Muscle fatigue can manifest as a burning sensation during your workout or as soreness in the days after.

Awareness of your RPE allows you to adjust your training intensity, potentially limiting muscle fatigue and pain.


Preventing Injuries

Monitoring your RPE can be instrumental in reducing the risk of injuries. By watching your RPE, you can adjust your workout intensity and avoid overexertion, leading to strains and more severe injuries. Here are some tips to prevent injuries:

  • Warm up properly to prepare your muscles.
  • Focus on proper form to reduce the risk of injury and improve your lifts.
  • Listen to your body and adjust your training plan when necessary.

By understanding and effectively using RPE in your training, you can get the most out of your workouts while optimizing recovery and minimizing the risk of injuries.
