In many posts Coach emphesises locked elbow, Iron cross or flys with rings are supposed to be performed with straight ,locked elbows. If I try to do it It feels like I'm about to dislocate my elbows, most of the muscle tension disapears and the weight hangs on my elbow, is this how it should be? am I prepering my joints to take most of my weight? It seems imposible to me, I'm more than half a way to the iron cross but if I tried to lock my elbows I would dislocate it,or maybe there's some specific technique to activate muscles that would support the hold?
Thanks
