Stability Ball Knee Tuck

Instructions for proper form

1. Start by placing your shins on the stability ball and your hands on the floor, aligning your shoulders above your wrists. 2. Keep your body in a straight line from the head to the toes, engaging your core. 3. Pull your knees towards your chest by rolling the ball inwards while contracting your abdominals. 4. Hold for a moment at the top of the movement, ensuring your back remains straight. 5. Slowly return to the starting position, controlling the movement as you extend your legs back out. 6. Repeat for the desired number of repetitions.

Common mistakes to avoid

1. Allowing your hips to sag or rise excessively, which can lead to back strain. 2. Using momentum instead of engaging your core muscles. 3. Not keeping the body in a straight line, resulting in poor form. 4. Allowing your head and neck to droop forward.
