About this machine

The Leg Extension / Leg Curl from the STEEL series is a combination machine for the front and back of the thighs. One machine trains the quadriceps with leg extensions and the hamstrings with leg curls. A compact design with a pair of rollers saves space in the leg area.

Why choose the Leg Extension / Leg Curl

Two leg exercises: leg extension and leg curl without moving to another machine.

Compact footprint: one machine instead of two, ideal for smaller gyms.

Adjustable back pad: aligns the knee with the pivot point of the arm for every user.

100 kg weight stack: as standard, optionally up to 160 kg.

Custom colours: a one- or two-colour frame and upholstery matched to your gym.

Who the Leg Extension / Leg Curl is for

It is ideal for small and mid-sized gyms, hotel and corporate fitness rooms or physiotherapy, where thigh training has to be covered in a small space. It suits beginners and advanced lifters alike.
