I must be honest, when I first saw that prone jacknife in the book I was pretty sure I wouldn't be able to do it. I mean, I'm a 210 pound woman who has not strength trained in a long time!!
But I did it, with a modification...
I rolled myself onto the ball and got it as close as I could to my ankles, but it ended up more like between my ankles and my knees. My shins, basically. Going through the prone jacknife reps that was has been AWESOME!! I'm still very sore, and aspire to get the ball closer to my ankles.
Remember that the little things we do each day matter.

Hello ladies, I just finished my 3rd workout and I can NOT do a prone jacknife yet. I guess my core isn't strong enough, but I cannot even walk myself out to an extended position without falling off the ball. Does anyone have a suggestion for an exercise to substitute for the prone jacknife until my core is stronger? Or perhaps a modification to the jacknife that might make it more manageable?
