Brace your core, press lower back into the floor. Slowly lower knees to one side, keeping shoulders down. Pause at a comfortable stretch. Engage obliques to return knees to center. Repeat on the opposite side.
To maintain proper spinal alignment, actively press your shoulders firmly into the floor throughout the exercise, preventing them from hiking up towards your ears. Control the descent of your knees, resisting the urge to drop quickly, which helps engage your core and prevents lower back strain. Initiate the movement by drawing your belly button towards your spine to stabilize your torso and maximize oblique activation. Keep your knees in contact with each other during the movement to ensure you're targeting your obliques and avoiding unnecessary hip movement.
