Machine Torso Rotation

The Torso Rotation (Machine) trains controlled trunk rotation while the pelvis is stabilized by a seat and pads. Unlike a cable woodchop, the movement follows the machine pivot rather than a diagonal cable path.

Targets: Core
Equipment: Machine
Type: Isolation

Step by step

How to do the Machine Torso Rotation

Adjust the seat, thigh pads, and starting angle so the machine pivot aligns comfortably with the torso.
Sit tall with the pelvis square, secure the legs, and hold the handles or press the upper body against the rotation pad.
Rotate the torso through the machine arc using the abdomen while keeping the hips and knees facing forward.
Pause at a controlled end range without bouncing or forcing farther rotation.
Return slowly to the start, complete the set, and reset the starting position to train the opposite side.
