In resistance training, volume is defined as the total work performed, calculated as sets × reps × weight.

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

Answer: (B)

Volume is the total work performed in resistance training, calculated by multiplying sets, reps, and weight. This captures the overall amount of work your muscles do during a session, so it increases when you add more sets, more repetitions, or lift heavier loads. For example, 4 sets of 10 reps with 50 kg equals 2000 kg of work (4 × 10 × 50). Density, in contrast, relates to how tightly you schedule work in time (such as rest periods or time under tension per unit of time), not the total work. Load is the weight used in a given lift, a component of volume but not the total work by itself. Intensity refers to how hard you’re working, often expressed as a percentage of your max, which describes effort per repetition rather than total work across the workout.
