Thanks for the replies.
God damn thats a sick pic! I wonder if his back is rounded on that, difficult to tell with the barbell in the way.
My thoughts on the exercise are that you are supposed to used a rounded back but use very light weight to strengthen the small deep muscles of the spine? On the other hand going to the range of motion shown in that picture with the back kept straight and rigid would be an excellent flexibility exercise for the hips.
Unfortunately there are no pics in “a system of multiyear training in weightlifting” of the exercise.[/quote]
The amount of weight on the bar tells the storey.
I have used these sometimes with heavier weights, round back, less range of motion. Reason is that normal GMs, round or straight, SLD, actually any deads or pulls even hypers tend to work my hammies tighten my hammies more than my back. This was the only exercise that worked my lower (actually mid erectors etc) back without tightening my hammies. I found my hammies were more stablising but my back felt good. I used a couple of plates on the bench lifting my hips a bit more,but still had my weight on my butt.
Actually most OL programs tend to use GMs with lighter weights than you usually expect.
