To learn to move as one and to use both arms at once work with a friend while you are holding a rope or belt using both hands at about a foot distance from each other (and by that I mean the width between your feet when you stand comfortably) Now survive attacks and attack yourself as you are holding the rope. The twists will tell you if you are twisting the body and the width will force you to work with both hands and teach you many possibilities. Another thing is to cope with the rope being grabed and live up to the cartoon “I’ve got you ! On the contrary I’ve got you” Have fun and remember: if you are not enjoying yourself you are doing something wrong. This is of course from a guy who goes to his happy place where he is hit by Misha so take it as you like.
