The recommended RPE (Rate of Perceived Exertion) exertion level range for effective exercise falls between levels 2 to 5. This range indicates a moderate intensity of exercise where individuals can maintain a conversation while engaging in physical activity but still feel they are putting in a reasonably challenging effort.

Exercising within this RPE range is essential for building endurance, improving cardiovascular health, and encouraging consistent participation in physical activity. When individuals work within this level, they can effectively benefit from their exercise regimen without overexerting themselves, which can lead to fatigue or injury.

Other ranges either fall too low or too high. For instance, levels below 2 may not provide enough stimulus for improving fitness, while levels above 5 might indicate a high-intensity effort that could be unsustainable for many individuals, particularly those who are new to exercise. Thus, targeting an RPE of 2 to 5 strikes a balance that allows for effective training while also promoting safety and long-term adherence to an exercise program.
