Part of what makes a GHR good is that it uses the hamstring at both ends. I think a lot of folks perform them by first doing a hip extension then a knee flexion type movement. That and I agree with Steven. Also, don't GHD sit ups work the rectus femoris and the abs, kind of the opposite things to the GHR, except it doesn't work the whole quad so much.
