i have a roman chair and thought i was doing back extensions but after seeing this video

http://media.crossfit.com/cf-video/CrossFit_GHD.wmv

i realize i'm actualy doing hip and back extensions. SOOOOO.... should i continue to do hip/back extensions or should i isolate them and do some of each?
when we do the filthy fifties and they ask for back extensions [i feel like an idiot typing this] i guess i should do back extensions "duh"

i'm still confused...

Re: Hip extension/back extension question

Ya, I'll admit I always do hip extensions when it calls for back extensions.

Re: Hip extension/back extension question

I can't remember specifically where I read this, but the term "back extensions" is not used literally, but inclusive of hip extensions. Take this as my $.02.

Typically, back extensions means hip extensions in a WOD. Hip extensions, with the lumbar back locked in isometric contraction, is how the back is typically used in fitness and sport. You are training the back in the way it is meant to be used.

True back extensions as shown in the video are obviously completely different. These are also good to work, but probably not in the high volume such as you find in a WOD.

I did true back extensions for Michael once and it slowed my time by a good 6-8 minutes. Now I do "hip" extensions for high intensity work and save the "back" extensions for maybe a set in the CFWU or supplemental work.

Re: Hip extension/back extension question

I don't have a GHD, I use my bench across my upper thigs, with the back of my feet being held by a safety pin in my power rack. Since the bench isn't very high (maybe 20" at most), I can't go down so much, so I think I keep my arch and only do "hip" extensions.

Re: Hip extension/back extension question

Isn't both of them that thing when you are on a machine and you bend from the hips forward and than back up. Just moving your upper body back and fourth and you are not standing?
