thanks for this question & the responses - I was wondering the same thing too.

I'd abandoned the prone jacknives because 1) the first time I tried was levelled with a screaming exertion migraine and 2) I kept falling off the ball.

I think my ball's on the big side for these workouts, but I also see I was trying to bring the ball too far in. I'll try it again.

The trouble I have with most ab exercises is I can not have my head lower than the rest of my body if I'm exerting. Instant headache. The best I can do is flat on my back.

I'll try the additional extension on the crunch with the ball though. I just didn't find the ball crunches challenging at all.. again though, i'm worried about the sudden onset of pain at putting my head back when my BP is up.
