I Am Not The Only One Who Doesn't Recommend Crunches

I haven't recommended crunches in over a half decade.  But, you still see many people doing them, along with trainers encouraging them.  Why?  You can feel the muscles fatigue and burn, I guess.  In this article about crunches, well known spine biomechanist, Stuart McGill discusses why they are so bad for the spine.  Additionally, crunches are a poor exercise choice because they reinforce poor posture, and exacerbate trunk muscle imbalances and poor movement patterns.  Oh, and they don't do a damn thing for the fat you have in your mid-section!
