RPE conversion chart — RPE, RIR, velocity loss, last-rep velocity
All four common effort languages on one chart — RPE 5.5–10, RIR 5–0, velocity loss 5–45 %, last-rep velocity 0.52–0.25 m/s. Drop a finger on any row to read across.
Four scales for the same dimension — perceived exertion, reps in reserve, percentage velocity loss, and the velocity of the final rep. They all measure how close a set was to failure; they just use different units. Stacked side-by-side on the same easy → maximal axis, a finger drop in any bar shows the matching value in the other three.
Use as a coaching reference when programs written in one language land with athletes who learned a different one — or when you’re combining objective (velocity loss / last-rep velocity) and subjective (RPE / RIR) measures in the same session. Velocity numbers shown are back-squat (low-bar) reference; the shape generalises, the absolute values shift by lift.
