How to stop on the lunge line without coming in.?

do some serious ground training with a rope halter. what i do with my horses is walk, expect them to walk with me, but when i stop i wiggle the rope, i dont shank or pull, just wiggle it, and if they dont stop with me i wiggle it a little harder until they back up. it teaches them about your personal space too. so when he;s on the lunge line, when you stop walking and turning with him he should come to a halt. if he turns to come into you, wiggle the line, wiggle it a little harder if he doesnt pay attention. make sure he understands that it cues him to stop and backup before you try it with the lunge line though. hope that helped!

You can either use a whip or you can use your lunge line (I prefer to use a long lead rope instead a lunge line as its easier to deal with the horse that way, while your training.) I also prefer NOT to use the whip, while I am training my horse and it seems better in my opinion. But any way, when you stop him as soon as he stops and walks to you wiggle the rope starting softly and if he continues to walk forward wiggle it harder till he stops. While you are wiggling the rope hold your other hand up like a stop sign and say "STAY". So when he finally stops due to your harsh tone and the wiggling of the rope then YOU walk up to him and praise him. After long enough all you will have to do when you stop him is hold up your hand and say "stay". It works that easy (:

Just flicking/pointing my whip towards my horse's shoulder usually solves this for me when he wants to try turning in. Pointing at the shoulder doesn't drive him forward, since the whip is not behind him.

Also, he was trained halter as a youngster, so he knows that when I raise my lead hand, he should freeze in place. This helps on the lunge too. Certainly a cue you can work on in groundwork.

Say "woah"

and try some pat parelli work. My horse goes and stops on voice commands now.

You can also take a long whip and go on the other side of the round pen with it sticking out and the horse will stop and probably back up.
