Crunch - Legs On Exercise Ball

Using an exercise ball to support your legs helps you maintain better posture and engage the core without straining your neck or back.

Instructions

1. Lie on your back with your legs bent and resting on an exercise ball.
2. Place your hands lightly at the sides of your head, elbows tucked slightly in.
3. Press your lower back into the floor to anchor your position.
4. Curl your upper body upward, lifting your shoulder blades off the floor.
5. Squeeze your abs at the top, then lower slowly back down.
6. Avoid using momentum; focus on controlled reps throughout.
