Chair Seated Side Crunch

Sit upright near the front edge of a sturdy chair with your feet flat on the floor.

Place one hand lightly behind your head and let your other hand rest on your thigh for support.

Engage your core and slowly lift one knee up toward the ceiling while crunching your torso sideways to meet it.

Focus on bringing your elbow toward your opposite knee to fully contract your oblique muscles.

Lower your leg and torso back to the starting position in a smooth, controlled motion.

Complete all your repetitions on one side before switching to the other.
