The leg extension targets the quadriceps in isolation while seated on the machine.
Seated on the machine, back against the backrest, pad positioned above your ankles, with the axis aligned with your knees.
Extend your legs until they are horizontal, hold for a second, then lower slowly.
Hold onto the handles to stay seated and control the descent rather than letting the weight drop.
