About this machine

The Rotary Torso from the STEEL series is a machine for training the obliques and rotational core strength. The user sits with the legs fixed and rotates the trunk against the selected resistance to either side. Rotational strength matters in almost every sport, from tennis to combat sports.

Why choose the Rotary Torso

Obliques: targeted training that is hard to do with free weights.

Leg and pelvis fixation: the movement comes only from the trunk, not the hips.

Both sides: set the rotation to the left or right and even out differences.

Controlled range: safe rotation without sudden spinal movements.

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

Who the Rotary Torso is for

Athletes, golfers, tennis players and fighters who need strong rotation will value it, as will regular members who want a solid core. In a gym it completes the ab and back area.

Frequently asked questions

Which muscles does it work?

Mainly the internal and external obliques, assisted by the deep back muscles.
