Re: Getting racked taking ukemi....
Wait ... what rank are you? never out pace your ability or let a nage inflict unwarrented pain!!
maybe your nage is taking you too quickly to the mat and has not allowed you to learn the ukemi for that, my advice is to take some extra practice on ukemi.
i teach it where the uke gets in seiza, then rises slightly, then one arm goes behind the back and the other goes across the body, the angle is much like when you take the technique IE left arm behind, right arm out sliding towards where the left arm should be in a sincere tenkan movement.
