What term refers to the amount of resistance used during an exercise, often expressed as a percentage of maximum effort?

• A. Load
• B. Intensity
• C. Volume
• D. Frequency

Answer: (B)

The main idea being tested is how hard you are working relative to your maximum capability. This is captured by intensity, which describes the resistance you use as a percentage of your maximum effort (for example, 75% of your 1RM). Intensity directly reflects how challenging the lift is and helps determine the training adaptation you’re aiming for. The other terms describe different aspects: load is the actual weight used, which can be measured in kilograms or pounds but isn’t inherently a percentage of max; volume is the total amount of work done (sets × reps × load); and frequency is how often you train. So the measure that fits the description—resistance expressed as a percentage of maximum effort—is intensity.
