You practice it first by absolutely in no way ****ing it back. Try throwing it with absolutely none of that.
What youll notice is that after a while youll be throwing it, then your body will naturally adjust itself to move the body first and then your arm will lock into position without moving and it will line up with the side of your body to deliver to the target. Its almost like just rotating your shoulder then everything falls into place. Once you learn to do it that way you'll also will be able to throw it out of sight so good that when you lead with ti they wont be able to tell whats coming at them. The natural alignment of your body will also allow a harder hook.
After you learn that then just do what you normally do. Step in>Bob/Slip>Hook Itll be out of sight since youre close theyll have trouble seeing it.
