The reason that crunches work is that it balances the weight load on your back - so if you have a strong set of stomach muscles, the back doesn't have to work as hard to support the body.

I had back issues for the longest - and now that my workout routine includes some brutal core work - back and stomach - I don't have as many issues with my back.

Thanks for the info. Hmmmm, seems as if I’d better get to work if I want to get my back problems under control.
