Which Borg RPE value corresponds to Moderate intensity?

• A. 14+
• B. 9-11
• C. 6-8
• D. 12-13

Answer: (D)

RPE is a subjective gauge of how hard you feel you’re working during exercise. Moderate intensity sits in the middle of the Borg scale: you’re breathing a bit harder than normal and your muscles feel like they’re under some load, but you can continue at the pace and you can speak in short phrases without gasping. If you were at the lighter end, talking would be easy and you wouldn’t feel much strain; if you were at the higher end, talking would be very hard and you’d feel you’re near your limit. So the mid-range level best matches moderate effort.
