I am having a difficult time seeing the difference between the "good" and "bad" example of the GHD situp in the exercise video. Any help explaining the difference between the two would be appreciated, thanks.

Can't load it for some reason. I think it was a bend in the knees on the bad form.

Yea it looks like the knees are the main difference to me.

It also appears as if she moves up much quicker in the good version, I'm not sure if that is part of it.

I think' like you guys said, the bent knees, which will take stress off of the hip flexors and lower abs on the initial drive up and transfer it to the legs. The quicker concentric movement is due to the explosive firing of the hip flexors from the bottom position, which doesn't seem possible from the bent knee bottom position. Hope that helps

Brian,

Exactly. You have to straighten your leg to fire the hip flexors, which initiates an explosive upward movement. If knees are bent, your hip flexors are taken out of the movement, resulting in increased and dangerous shear in the spine.

Dang well that ruins the little replacement machine I had set up with my bench. Are there any good ways to do another exercise here to replace it? Such as v-ups or something?
