Why I feel neck muscles pain after doing abs exercises?
I tried to focus on my abs to elevate my upper body, but still experience neck pain.
Any tips to avoid the muscles pain?
I get the same. Good tip for you. Keep your tongue pressed against the roof of your mouth while doing the exercises. It prevents unnecessary pulling in the neck. Not holding your neck but rather touching your forehead while doing the exercises also helps.
What kind of ab exercises are you doing when your neck hurts?
