When I do Airborne Jacks, my knees get a little bit of a stress going on. If I do Airborne Jumps, no problem. But when I do the Jack, it feels like there's stress at the knee joint at the point where my legs are their widest apart and highest off of the floor. I'm not even close to going as wide as Cathe goes, either. Sometimes I just sub Jumps for Jacks because they don't stress my knees.
So is this a form issue, or do some moves just stress certain people based on how they're built, or what? Any ideas?
