What do you think of this exercise? Has anyone here tried it?
Picture this: The great Olympic weightlifter Vasily Alexeevï¿½??s ponderous body draped over a gymnastics long horse with his feet wedged between the stall bars of an unbelievably archaic training gym in Moscowï¿½??s Lenin Institute of Sport. With four hundred pounds precariously perched behind his head, he explodes for five reps of back raises.
There is virtually NO hip extensor involvement, only pure erector spinae contraction. That means 1) tremendous low back limit strength and speed-strength is developed far beyond what any other low back exercise could possibly accomplish, and 2) virtually NO trauma to the tenuous intervertebral discs of the lumbar spine, which is something no other low back exercise ever conceived can claim.
So, I see that most of the flexion occurs at the thoracic spine and I guess that despite flexion of the lumbar spine, end-range lumbar flexion is avoided, right?
