Sitting Side Crunch on a Padded Stool

Instructions

1. Sit tall on a padded stool with hands behind your head and feet flat on the floor.
2. Brace the core and laterally flex the spine, crunching one elbow toward the hip on the same side.
3. Hold briefly at the peak contraction, then return to upright.
4. Alternate sides for each rep or complete all reps on one side before switching.
5. Avoid pulling on the neck — let the obliques do the work.
