People Also Ask

What does training to failure mean?

It means taking a set until you physically can't complete another rep with good form. It's a high-intensity technique used to maximize muscle fatigue.

Is training to failure good or bad?

It can drive muscle growth but is very fatiguing, so most lifters use it sparingly rather than on every set to allow recovery.

What's the difference between failure and RIR?

Failure is zero reps in reserve (RIR 0) — the point where you can't do another rep. RIR measures how many reps you stopped short of failure.
