How can I add weight to my crunches without using a medicine ball?

I don't own a medicine ball and would like to add weight to my crunches so I don't need to do 800+ of them to feel anything. I do all different kinds of core exercises and I'd like to add some resistance to them.

Any ideas? I've tried free weights but that just feels really uncomfortable.

Thx a mill.

I know how to do a correct crunch, my neck does not hurt after, and my abs are really strong. I do all different kinds and work different areas... think about it. Several sets of 25 on each area... dumbass!

I think crunches are more effective than sit-ups. Maybe you just have to do different kinds, and not too fast. It is usually more effective the slower you go. Here is a link with some different kinds of crunches
