You have a few options: grab the tail of the wrist lock with the free hand and unwind the wrap, pull the locked hand down, fingers straight up, or if your shoulder are above the locked wrist, unwinding the wrap by reversing the pathway of the locked wrist. Whichever works best for you, make sure your weight is mostly in the other strand so the ‘lock’ softens. It’s also easier if your shoulders are in line with the locked wrist. Happy training!
