Answer: C - On the original Borg Scale - also known as the Rating of Perceived Exertion scale - a RPE of 12-16 would correspond with the 55-90% target heart rate range suggested by the ACSM. On this scale a 12 would rate as “somewhat hard” and a 16 as between “hard” and “very hard”. On the 10 point Borg scale, this intensity would be rated between a 4 and an 8.
