Why choose the ISO Seated Triceps Extension
Independent arms: two-arm or single-arm work that evens out differences between arms.
Elbow pads: hold the upper arms in place and isolate the triceps.
Adjustable seat: aligns the elbows with the pivot point of the arms.
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 ISO Seated Triceps Extension is for
Advanced lifters and bodybuilders who want symmetrical arms will value it, as will gyms that want to equip the arm area with premium ISO machines. Single-arm use is also practical when returning from an injury.
