The real problem? You’re doing crunches all wrong.
For better or for worse, the key to killer abs is strengthening your core. But if you’ve tried every variation of crunch under the sun, and each is feeling just as daunting on your neck, you are likely feeling discouraged from the exercise.
Most people perform a crunch from their upper body, rather than their actual abdominals. This means your neck muscles are getting worked in a way you don’t want. Try tucking your neck in next time to reduce muscles activity in your neck.
