Dumbbell side bend

Core · Dumbbells

Sets, reps and RIR

Sets3
Reps10 to 20
RIR1 to 2

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.

Enter a set to see the estimate.
