Thank you but i think that yonkyo and gokyo are one of the main wrist locks and i nevewr heard of Sayu-nage can you describe it
Not in the form of Aikido i study, we dont practice either; Yonkyo doesnt work on everyone(including a very flexible young woman at my dojo). So its basically just the 3 i listed with us, unless you include Kote-gaeishi.
And sayu nage is kinda like kokyu-nage, but with the back of your arm, versus the inside; does that make sense?(and its not my favorite, haha)
