Roman chair side bend

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: Obliques.

Secondary: Lower back.

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.
