Seated Triceps Extension
The Seated Triceps Extension from the STEEL series is a machine for isolated triceps training. The elbows rest on a pad and the movement comes only from the elbow joint, so neither the shoulders nor the chest can help. It is a machine alternative to the skull crusher, without the strain on the elbows of lowering a bar behind the head.
Nothing has to be selected — click an option again to clear it and we will recommend one. This choice applies to every machine in your request by default; mixing colours within one set is arranged individually. Any RAL shade on request, photos show the standard black frame.

Why choose the Seated Triceps Extension
Elbow pad: keeps the upper arms in place and isolates the triceps.
Elbow-friendly: a guided path with no awkward bar position behind the head.
Adjustable seat: aligns the elbows exactly with the pivot point of the arm.
100 kg weight stack: as standard, optionally 120 kg.
Custom colours: a one- or two-colour frame and upholstery matched to your gym.
Who the Seated Triceps Extension is for
It suits gyms that want a dedicated triceps station. Together with the Seated Triceps Dip (SD22) and the Seated Biceps Curl (SD21) it creates a complete arm area.
Frequently asked questions
How does it differ from the SD22?
