Single-leg leg extension

Sets, reps and RIR

Machines and cables hold the path for you, so you can work closer to failure than with free weights.

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: Quads.

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.
