The cable seated twist builds true rotational core strength by keeping constant tension on your obliques and abs throughout the entire movement. Master this pattern and you will develop the kind of functional midsection stability that carries over to every athletic and daily task you perform.
Sit sideways to the cable stack, feet flat and knees bent at 90 degrees, and grip the handle at chest height with both hands extended in front of you.
Brace your core and keep your arms straight as you rotate your torso away from the cable, driving the movement from your obliques not your shoulders.
Pause briefly at the end range of rotation, feeling full tension in the working side of your core.
Slowly return to the start position under control, resisting the cable pull rather than letting it yank you back.
Common mistakes
Rotating with bent arms by using the arms to pull the cable instead of the torso, which shifts load away from the core entirely so keep arms locked straight throughout.
Allowing the hips to twist by not anchoring the lower body, which turns this into a hip movement rather than a core movement so plant your feet firmly and keep your pelvis square.
Using a weight that is too heavy by sacrificing range of motion and control for load, which reduces muscle activation so choose a weight that lets you feel each rotation fully.
Pro tip — At the end of each rotation, exhale sharply and think about pulling your bottom rib toward your hip bone to maximize oblique contraction before returning to start.
