Which FITT element is specified as 60-85% of maximum heart rate?

• A. Time
• B. Frequency
• C. Intensity
• D. Type

Answer: (C)

The main idea being tested is how the FITT principle describes how hard you work during exercise. Intensity is the part of FITT that defines effort level, often shown as a percent of your maximum heart rate. Saying you should exercise at 60-85% of max heart rate sets how hard the workout should feel and how your body is challenged, which is exactly what intensity describes. This range is a common aerobic conditioning zone, meaning it’s enough to improve cardiovascular fitness without being too easy or unsafe. For example, estimate max heart rate as 220 minus age; a 25-year-old would have about 195 bpm, so 60-85% is roughly 117-165 bpm. Time is about how long you exercise, frequency is how often per week, and type is what activity you do, so those don’t specify effort level in the same way.
