doing crunches wrong

Try this technique

Lie on your back with your legs raised, knees bent and feet flat on the ground. This position is good as it puts the pelvis and therefore the spine into a neutral position. Now place your hands on your thighs with your arms straight. All the movement must come from your stomach and you activate your stomach and slide your hands up your thighs towards the knees. Everyone’s body proportions are different so go as far as you can so that your shoulder blades are off the ground and this should mean you can touch your knees. If you can’t don’t worry, it will come with time, just go as far as your stomach will take you.

Do squats instead... seriously

If you've gotta do crunches, I always used to put my hands *at* my ears, or i'd roll up a towel and hold it behind my head. That should help

A training cue that I frequently used with others is to lift your sternum up, not your head ("lift your sternum straight to the ceiling, everything else will follow".  Also, place your fist under your chin to "measure" a neutral position.  PLace the other hand on your abdomen to feel the muscles contract as you lift.  Also, don't forget to breathe properly (remember, exhale on exertion)
Many may tell you to pick a spot on the ceiling to focus on, I say no, b/c you'll usu. pick a spot that is directly above you and when you contract, that is what causes what I call the turtle affect (sticking your head out like a turtle)

Good Luck

Maybe my Abs will but I surely won't.

Do planks instead.

Great ab workout, no strain on neck.
