When prescribing load using relative intensity, which metric is most commonly used?

• A. Percentage of 1RM
• B. Kilograms only
• C. Repetition maximum velocity
• D. Relative intensity expressed as percentage of 1RM or max effort

Answer: (D)

When prescribing load using relative intensity, you’re tying the effort to what the lifter can actually do at their best. The most common approach is to express the load as a percentage of the lifter’s 1RM or as a max-effort level (often captured with an RPE scale). Using a percentage of 1RM provides a clear, objective reference that translates across sessions and days—so if you plan 80% of 1RM for a set, you’re aiming for a defined fraction of that person’s maximum capability. If you don’t know the exact 1RM or you want to adjust for daily readiness, a max-effort rating still communicates how hard the work is relative to capacity. Kilograms alone are an absolute measure and don’t account for individual strength differences. Repetition maximum velocity is useful in velocity-based training but isn’t the standard method for prescribing relative-load intensity in most programs. So the typical choice is expressing relative intensity as a percentage of 1RM or a max-effort level.
