Description

A core exercise performed on a stability ball to target the abdominals.

How to Do Stability Ball Crunch (Full range hands behind head)

1
Setup
Position yourself on a stability ball so your lower back is supported, feet flat on the floor, hip-width apart, and knees bent at 90 degrees. Your hips should be slightly lower than your knees.
2
Setup
Place your fingertips gently behind your head, elbows wide, ensuring no pulling on your neck. Your head should be in a neutral position, looking towards the ceiling.
3
Exhale and engage your core, slowly crunching your rib cage towards your pelvis by flexing your spine, lifting your head and shoulders off the ball. Keep your lower back pressed into the ball.
4
Continue crunching until your shoulder blades are fully off the ball and you feel a strong contraction in your abdominals. Maintain a slight gap between your chin and chest.
5
Inhale as you slowly and with control reverse the movement, extending your spine and lowering your torso back to the starting position on the ball. Allow your shoulder blades to gently touch the ball.

Tips

Focus on initiating the movement from your abs, not by pulling with your neck or using momentum.
Maintain constant tension in your core throughout the entire range of motion, avoiding resting completely at the bottom.
Visualize bringing your sternum closer to your belly button to maximize the abdominal contraction.
Keep your elbows wide to prevent pulling on your neck and to ensure your focus remains on abdominal engagement.

Common Mistakes

×Pulling on the neck: Avoid yanking your head forward with your hands; instead, keep your hands gently supporting your head with wide elbows and let your abs do the work.
×Using momentum: Do not rock your body or use a jerking motion to crunch up; perform the movement slowly and with control to fully engage your rectus abdominis.
×Crunching too high or too low: Crunch only until your shoulder blades lift off the ball to isolate the rectus abdominis, rather than sitting up fully or barely moving.
