RPE-based training – What is the Borg RPE Scale and how can I apply it to my workouts?

April 21, 2022

What is RPE?



The Borg Rating of Perceived Exertion (RPE) Scale is a subjective scale which is used to estimate one’s own level of exhaustion. The original scale was a 6-20 scale, relating to heart rate, whereby 6 denotes a resting intensity and 20 is maximal intensity. For simplicity, there exists a modified scale of 1-10.

RPE can be applied to both resistance exercise and cardiovascular exercise and is usually obtained either immediately following a bout of exercise or after the session is complete (session-RPE). The Borg Scale defines an exercise to be of a particular intensity based on the range it sits in (see figure below for details). The RPE scale offers an intuitive approach to exercise in the form of self-monitored training intensity.

It should be noted that despite distinct categories of light, moderate and hard intensity, the RPE scale is more accurately represented as a spectrum.

Given time and practice, the Borg RPE Scale can yield more accuracy and consistency as one’s perception of exertion will improve. Coaches may also ask for a client’s RPE to gauge their progress and difficulty of the session.

 

How can I apply RPE to my own training?


RPE can be set at a pre-determined value prior to performing a set or bout of exercise. On days when energy levels are diminished, or when working through an injury, deliberately working at a low RPE could be a viable strategy to avoid excessive fatigue and prevent further injury. An example of this would be acquiring a knee injury and decreasing the amount of weight lifted on squats, effectively lowering the RPE.

On the other hand, on days where energy levels are high and performance seems to be at its peak, training at a high RPE could be beneficial. For instance, testing 1-repetition-max performance requires RPE 10, therefore it would be more appropriate to perform this on days with higher energy levels to avoid injury.

This method of adjusting the session intensity as you go is a sustainable way to approach training and may be appropriate for the majority of people. It is important to keep in mind that for people with specific training goals and deadlines such as competitions, abiding by the programmed intensity leading up to competition could yield a better outcome.

If strength progression is a goal, an individual may notice that their RPE for a given set performed each week may be slowly dropping, implying that strength has increased and therefore it would be time to increase the weight. This method of tracking progression may also apply to other forms of exercise such as running. Performing a 5km run may invoke a post-session RPE of 9, but after completing the same run frequently for 2 months at the same pace, the RPE may drop to 7, indicating that it is time to increase the pace or distance.

 

How hard should I be working?


RPE should be varied across a training program such that each week is not consistently at a high RPE in order to avoid burnout and fatigue. It is impossible to sustain a session-RPE of 9-10 for every session. With this in mind, the optimal RPE range to work within would be 6-10. This recommendation varies slightly throughout the current literature and there also exists newer studies which investigate low RPE coupled with high frequency training for hypertrophy. However, for the most part, training at a reasonably high RPE will return good results and let one feel accomplished after the workout.

 

RPE vs RIR


RPE is often used synonymously with Repetitions in Reserve (RIR), another method of subjectively scoring intensity. RIR describes the number of repetitions which could have been performed at the end of a given set, ie. The number of repetitions that were “left in the tank”. For example, after completing a set of 5 repetitions on the deadlift, one may think they could have done 2 more repetitions if they really tried. In this case the RIR would be 2, and their RPE could be somewhere between 7-9 depending on how they felt after the set. There is a slight discrepancy between these two subjective measures, however both will help gauge a similar finding.

The Borg RPE Scale is extremely useful for day-to-day exercise sessions. It can be used to track exercise progression and to adjust exercise intensity accordingly. It also encourages workouts to be completed at lower energy/effort levels on days where we simply aren’t feeling it, reminding us that doing something is definitely better than doing nothing.

Exercise for Mental Health: A Vital Component for Busy Individuals In the hustle and bustle of modern life, juggling work, family, and social obligations can leave little room for self-care. However, prioritizing regular physical activity is crucial for maintaining not just physical health but also mental well-being. While the demands of a busy schedule might make it challenging to incorporate exercise into daily routines, the profound benefits it offers for mental health make it a non-negotiable element of a balanced and fulfilling life. The Connection Between Exercise and Mental Health Exercise has long been celebrated for its physical health benefits, including weight management, cardiovascular health, and increased strength and endurance. However, its impact on mental health is equally significant and often overlooked. Research has shown that physical activity can alleviate symptoms of anxiety and depression, improve mood, enhance cognitive function, and reduce stress levels. Some of the benefits of exercise on mental health include: Mood Enhancement: Engaging in physical activity stimulates the release of endorphins, often referred to as the "feel-good" hormones. These chemicals act as natural mood lifters, helping to combat feelings of sadness and anxiety. Stress Reduction: Exercise provides a healthy outlet for stress relief. Physical activity increases the production of norepinephrine, a chemical that moderates the brain's response to stress. Additionally, the repetitive nature of many forms of exercise can have a calming effect, akin to meditation, helping individuals feel more relaxed and centred. Improved Sleep: Regular exercise has been shown to improve sleep quality, which is closely linked to mental health. A good night's sleep is essential for cognitive function, emotional regulation, and overall well-being. Cognitive Benefits: Exercise has been found to boost brain function and protect against cognitive decline. Physical activity increases blood flow to the brain, promoting the growth of new neurons and enhancing synaptic plasticity. This can lead to improved memory, concentration, and overall cognitive performance, which are particularly beneficial for busy individuals juggling multiple responsibilities. Social Interaction: Many forms of exercise, such as team sports or group fitness classes, provide opportunities for social interaction and connection. Building relationships and engaging with others in a positive, supportive environment can have a significant impact on mental health, reducing feelings of isolation and loneliness. Exercise is an Antidote to Burnout When work and personal life pile up, burnout becomes a real concern. The feeling of being constantly “on” with no time to recharge can negatively impact both your mental and physical health. Exercise provides a much-needed escape. It helps you disconnect from work pressures and reconnect with yourself. Taking the time to move your body is a form of self-care that signals to your brain that you are prioritizing your well-being. As you engage in physical activity, your body releases tension, clears your mind, and gives you space to breathe—important factors in preventing burnout. Overcoming Barriers to Exercise for Busy Individuals For those with hectic schedules, finding time for exercise can be challenging. However, integrating physical activity into daily routines is possible with some strategic planning and creativity. Here are some tips to help busy individuals make exercise a priority: Schedule It In: Treat exercise as a non-negotiable appointment, just like any other important meeting or commitment. Block off time in your calendar for physical activity and stick to it. Consistency is key to reaping the mental health benefits of exercise. Incorporate Short Bursts: If long workout sessions are not feasible, aim for shorter bursts of activity throughout the day. Even ten minutes of exercise, such as a quick walk, stretching, or a mini workout, can contribute to overall mental well-being. Combine Activities: Look for opportunities to combine exercise with other tasks. For example, take a walking meeting, use a standing desk, or do bodyweight exercises while watching TV. These small changes can add up and help you stay active. Find Activities You Enjoy: Choose forms of exercise that you genuinely enjoy, as this will make it easier to stick with them. Whether it's dancing, hiking, swimming, or playing a sport, finding an activity that brings joy will increase the likelihood of making it a regular part of your routine. Set Realistic Goals: Set achievable fitness goals that align with your schedule and lifestyle. Start with manageable targets and gradually increase the intensity and duration of your workouts as you build confidence and stamina. Make It a Social Event: Involve friends, family, or colleagues in your fitness journey. Exercising with others can provide motivation, accountability, and an opportunity to bond over a shared activity. Conclusion Incorporating exercise into the lives of busy individuals is essential for maintaining mental health and overall well-being. The positive impact of physical activity on mood, stress reduction, sleep quality, cognitive function, social interaction, and burnout prevention makes it a valuable tool for anyone seeking to navigate the demands of a hectic lifestyle. By prioritizing exercise and finding creative ways to integrate it into daily routines, busy individuals can enjoy the mental health benefits that come with an active lifestyle. Remember, a healthier mind is a step towards a happier, more balanced life.  Blake Cocking Workers Compensation Specialist ‑ WA Team Lead (AEP, ESSAM) Exercise Rehabilitation Services ‑ WA

The Role of Load Management in Rehabilitation: A Framework for Returning to Function, and Injury Prevention. Load management is often associated with high performance sport, but its principles are just as critical in rehabilitation. Whether guiding injured workers back to work, older adults to independent living, or patients recovering from injuries, progressively and systematically managing load is essential for recovery, injury prevention, and long-term function. A major challenge in rehabilitation is balancing workload progression to optimise adaptation without overloading healing tissues. Sudden spikes in training load or returning to full activity too soon significantly increase the risk of re-injury. Exercise physiologists can use load monitoring, periodisation, and predictive planning to ensure a structured and safe return to work, life, or recreational activity. Understanding Load and How to Monitor It In rehabilitation, load refers to the total amount of mechanical and physiological stress placed on the body. This includes external load; the measurable work performed (e.g., weight lifted, steps taken, distance covered, time spent in physical activity), and internal load; the body’s physiological and perceptual response to that work (e.g., heart rate, rate of perceived exertion (RPE), pain, fatigue). Both external and internal load must be monitored to ensure that rehabilitation is progressive yet not excessive. One of the most useful frameworks for load management is the Acute: Chronic Workload Ratio (ACWR), which helps determine whether a patient is progressing at a safe rate or at risk of overload. A sudden spike in acute load (ACWR >1.5) increases injury risk by 2-4 times in the following week. Therefore, a gradual increase in chronic load (≤10% per week) is essential to build resilience and capacity. - Acute Load = The total workload over the past week. - Chronic Load = The rolling 4-week average of workload. - ACWR = Acute Load ÷ Chronic Load. Patients often underestimate how small spikes in activity (e.g., resuming full work shifts after time off, or inconsistent engagement in their self-management plan) can lead to flare-ups or re-injury, and by tracking ACWR, we can educate the patient accordingly and prevent excessive acute spikes while ensuring a steady increase in chronic workload, reducing the likelihood of setbacks and ensuring a progressive return to function. To apply these principles effectively, we need accurate and practical ways to measure and track load in real world rehabilitation settings. Unlike athletic settings, maximal strength testing (1RM) is often inappropriate in rehabilitation. Alternative methods include volume-based and time-based load tracking, perceived exertion and fatigue monitoring, and functional testing. - Monitoring total weight lifted per session (sets × reps × resistance). - Measuring time under tension for endurance-based activities. - Using exercise RPE and session RPE to gauge effort. - Reassessing movement capacity, endurance, and strength progression over time. Using subjective feedback alongside objective load tracking allows for better exercise prescription and progression. Asking the right questions can guide real-time modifications: External Load Questions: - How much activity did you complete this week? - How does this compare to last week? - Did you struggle with any tasks or exercises? Internal Load Questions: - How fatigued do you feel after sessions? - How long does it take you to recover? - Are you experiencing pain or discomfort, and how does it change with activity? Structuring Load Progression for Long-Term Success Periodisation is the planned progression of training load over time, ensuring continued adaptation without excessive strain. While typically used in athletic settings, structured periodisation is just as valuable in rehabilitation, helping prevent stagnation by adjusting workload over time, ensuring progressive overload while respecting tissue healing and recovery rates, and guiding return-to-work planning by matching rehabilitation loads with real-world demands. A structured approach allows us to compare a patient’s current workload tolerance to their end goal and reverse-engineer a safe progression plan. If a patient needs to tolerate X hours of work or Y level of activity, we can use their current capacity and reverse-calculate a safe, gradual progression timeline and by maintaining consistent, small increases in chronic workload, we minimise setbacks and ensure safe long-term recovery. Linear Periodisation is best suited for straightforward recovery cases with minimal variability in symptoms. While, nonlinear periodisation may be more practical for rehabilitation, as symptoms and capacity can vary day-to-day. - Linear Periodisation: Steady, predictable increases in intensity, volume, or duration over time. - Nonlinear (Undulating) Periodisation: Load fluctuates based on recovery, pain, and function. Applying Periodisation to Rehabilitation Planning Step 1: Establish a Baseline Identify current weekly workload (e.g., hours of tolerated activity, steps, resistance training volume) and functional deficits (e.g., strength, endurance, movement capacity). Step 2: Define the End Goal What workload is required to return to work, sport, or daily function? This could mean sustaining an 8-hour work shift, lifting a certain weight, or tolerating daily activities without pain. Step 3: Plan a Safe Progression Gradually increase chronic workload by ≤10% per week. Avoiding acute spikes (ACWR >1.5) to prevent setbacks. Monitor pain, fatigue, and function to guide daily and weekly adjustments. By integrating load monitoring, periodisation, and predictive planning, exercise physiologists can create safe, structured rehabilitation programs that optimise recovery, prevent re-injury, and guide patients back to work, sport, or daily life with confidence. Key Takeaways for Exercise Physiologists - Load management is essential in rehabilitation, not just in sports. - Acute vs. chronic load balance is key. Avoiding acute spikes prevents injury, while gradual increases build resilience. - Tracking external and internal load ensures a data-driven approach to exercise prescription. - Periodisation structures rehabilitation progression, ensuring steady gains without excessive strain. - Patient education on workload progression improves compliance and reduces re-injury risk.

How would I rehabilitate a wrist, hand or finger injury? Rehabilitating a hand injury is challenging due to the hand's essential role in daily tasks, including heavy lifting and precise movements. So, what are some key focuses to prioritise with rehabilitation of the hand and wrist? Understanding hand anatomy is essential. The hand consists of 27 bones: 8 carpal bones (wrist base), 5 metacarpals (palm), and 14 phalanges (fingers), all connected by ligaments and serving as tendon attachments. When an upper limb injury occurs, immobilization is necessary for recovery. This leads to reduced upper limb use, resulting in muscle atrophy, decreased strength and feelings of tightness or stiffness, along with discomfort. Not every movement requires a 'power' grip for strength and endurance restoration. Rehabilitation stages may involve using various objects to challenge the grip, facilitating a transition to dynamic everyday strength. The hand, as the most proximal structure of the upper limb, is crucial for daily tasks and fine motor control. A little tip that can help improve someone’s rehabilitation is implementing exercises that can incorporate a ball, broomstick or even different types of stationary! Rehabilitation for fingers, hands, and wrists varies for each individual.  A tailored approach, sometimes requiring minimal intervention or creative solutions, can lead to optimal outcomes.
