CrossFit Koncepts

I've had a lot of feedback on this month's class warm-up (it's all been very positive thank you) but everyone seems to be having trouble with the Hanging Leg Raise.  Take a few minutes to watch the video below to get some good pointers as well as acceptable substitutes for this exercise that you can attempt.  Other than that - Quit your whining and get you butt up there!?!? :)
