Exercise Ball Jackknife

1 - Start in a high plank position with your hands directly under your shoulders and your shins or tops of your feet resting on an exercise ball.
2 - Brace your core, keep your body in a straight line from head to heels, and avoid letting your hips sag.
3 - Slowly pull your knees toward your chest by rolling the ball forward underneath your legs.
4 - Pause briefly at the tucked position while keeping your shoulders stable and your core engaged.
5 - Extend your legs back out by rolling the ball away until you return to the starting plank position.
6 - Repeat for the desired number of repetitions while maintaining control and steady breathing.
