Neck Ache More Condition_symptoms Why Does My Neck Ache When Sit Ups On Gym Ball?

Why does my neck ache when sit ups on gym ball? - neck ache more condition_symptoms

Ive done squat for 4 days now in the gym ball. I'm so unfit.
Above all, the tone of my stomach.
The first day my stomach hurt, this shows it worked, now more tension in the neck. My stomach hurt now dosnt seam.

Is it because the use of instant messaging Crouching get to? Is this pain in my neck, because I'm too high?

Im not sure if I am doing well.

Thank you.
