Substitute for crunches
I was doing crunches faithfully until about a month ago when I was struck with a severe episode of vertigo. I'm over the worst, but I still get dizzy if I move my head strangely (lying down on the bed at night, swishing my hair out of my eyes, etc.) I was wondering if anyone had a suggestion for some sort of excercise that could substitue for crunches and that wouldn't involve moving my head around. Thanks for your help.
