Cable crunch

Sets, reps and RIR

Stop the set when position breaks, not when the muscle burns. Quality of position is the whole point.

RIR means reps in reserve: how many you could still have done when you racked it. RIR 2 is two short of failure.

Muscles worked

Primary: Abs.

Secondary: Obliques.

Estimate your one-rep max

Epley's formula, from a set you have actually done. It is an estimate, and it drifts above eight reps, so keep the input between one and twelve.
