Twists of waist with barbell or stick

Rotate the torso under control through the rib cage and waist while keeping the pelvis as stable as the variation allows. Return without bouncing. Prioritize control over speed. Maintain useful tension through the range and deliberately reset the starting position before the next repetition.

Do not turn the final repetitions into fast or partial movements. Aim to load abdominals and obliques without sacrificing position; at intermediate level, progress control first and then add load, repetitions or complexity.
