When a coach says an athlete needs to “lift heavy,” what does that actually mean?
For training maximal strength and gross force output, the target described here is moderate-heavy loading, typically around 75–90%, 1–3 reps in reserve (RIR), or RPE 7–9 for most athletes.
In practical terms, the final reps should involve some strain, but the set stops just short of a true maximal effort.
