From http://www.thedailybeast.com/newsweek/blogs/the-human-condition/2009/06/03/stop-doing-sit-ups-why-crunches-don-t-work.html :

“We stopped teaching people to do crunches a long, long time ago,” .... That’s because the “full flex” movement—the actual “crunch” part of crunches – puts an unhealthy strain on your back at its weakest point.

"And of course, when people do crunches, they rarely stop at one or two: in the quest for flat abs, they’ll churn out dozens at a time, bringing them ever closer to “flex intolerance”—so much pain and stiffness that it’s difficult to tie one’s shoes or bend down to pick a penny off the ground."
