You can also use a neck streacher, which is like side reigns, but you can set it to way loose or tight, its more forgiving too so the horse dosent feel traped, my horse carries his head high, and even though some of it is his attitude, when we put him in side reigns to ride, he tries to run back wards and pop and spin and do the hokie pokie horse version ahah, but hes okay with the neck streacher. But ive only used that once, mostly i do hand signals to him, hold steady contact with outside reign and keep slightly jiggling the inside reign by opening and closing my pinking and ring finger (the 2 the reigns are through), or touching it, while giving him inside leg like i want him to turn, but the outside reign wont allow it, till he gives in, then i let off the inside reign, but still keep contact on outside, then when he puts it back up, i do it all over.
