Thanks for all the advice. I do 100 crunches everyday and it takes me longer than two minutes. But, I am getting better. It seems like my torso is extremely long and I have such a long way to go that I end up doing a full sit up. I do the same as Huey Cobra and bounce my shoulder blades off the ground and come back up, and I do feel it in my quads when I am through. I will try keeping my head back because I do bend my neck. And it seems like I use my back muscles a lot to pull myself up.
