Repetitions in reserve and useful effort

THE STRONG TABLE / FREE RESOURCE COLLECTION / SEPTEMBER 2026 1 THE STRONG TABLE / TRAINING / 03 Repetitions in reserve and useful effort Learn to describe effort without needing to test failure. 01 / Understand the starting point Repetitions in reserve, or RIR, estimates how many additional repetitions you could complete with the same technique. It is not a pain rating, and it is not exact when you are new to lifting. 02 / Make the useful distinction Begin with a deliberately manageable load. Stop when movement quality becomes uncertain. Beginners can practice leaving several repetitions available before working closer to their limit. 03 / Put it into practice Compare your estimate with the next session: could you add a controlled repetition while keeping the same setup? Use this feedback to calibrate effort gradually. No maximal test is necessary. 04 / Review and adapt Record RIR alongside load and reps. Failure is optional for general training, not proof that a set counted. For heavy lifts, preserve sufficient rest and use appropriate supervision and safety equipment.

THE STRONG TABLE / FREE RESOURCE COLLECTION / SEPTEMBER 2026 2 THE STRONG TABLE / TRAINING / 03 Put the guide to work. A worked example, then your own next step. A practical example Goblet squat: 2 sets of 10, estimated 3 RIR, stable depth and breathing. Next time repeat the setup and try 11 if all remains controlled; avoid simultaneously adding load and reducing rest. Your decisions What task or goal do I want to improve? What is my starting point and what remains uncertain? Which detail changes my next useful action? What would make the action easier to repeat? When will I review it, and what would require earlier help? Use the platform Training: compare programs and technique guides. Daily: generate a session or arrange a week. Planner: calculate targets and select meals. Progress: record completed work. Learn: return to clinical reading when symptoms need professional assessment.
