Help! Lounging Problem with my new gelding!!!

Your position doens't matter as much to him as it does to you.  If he is walking in on you straight on use your lead or stick to start tapping his shoulder and neck.  If there is no response wack him a bit harder on the shoulder and neck but should he really push into you tap his jaw.  You shouldn't be moving at all around him.  Stand your ground and if he dives into you as he goes around don't jump out of his way use the lead or stick to tap him on the ribs to encourage him to round his body and arch around you.
 
Heres how I teach my clients.  Stand straight in front your horse.  He should be stopped and facing you about 4-6 feet out.  If he starts walking in BEFORE he is cued to do so back him up quickly with energy.  This does not mean you charge in there at him but use the lead to creat the energy and use your body to hunker down a bit and the weight of the lead and snap will move the halter enough to move him back.
 
Now that he is back where he belongs choose your direction.  Lets say to the left.  Hold up your left hand about shoulder high and shorten up your lead.  It needs to be slack but short enought that if he moves the wrong way he will fell pressure from the halter almost instantly.  Use your right hand either twirling the lead rope or using a training stick and start tapping the air next to his shoulder.  If nothing start tapping his shoulder.  This is where some horses will try to move into you to escape the pressure but keep you feet as still as possible and really smack his jaw line should he step into you.  If he runs the other way give a good pull release until he is facing you but don't pause before sending him off again otherwise they start thinking if they run the other way they get to rest.  When he goes the right way only let him move around you say a couple circles and then ask him to stop and bring him in to rub and reward him.
 
He already knows how to lunge so you have him there.  Its just getting him to realize that YOU know how to lunge and he can't get out of it.  I have found that the more you try and move  TO the shoulder the more confused the horse gets about what you are trying to tell him.  Especially if he is very well trained.  Stay in front or just at an angle to him so that you are still in front of him but barely off to one side.  When you change directions be firm with him and insist that he move off.  Don't be afraid that if you wack him he wont love you anymore, just go back and rub all over him after he makes a full circle and he will look to you for leadership just as he looked at his previous owner/trainer.  Horses love rules and look for the one who can give them without anger or bias and enforce them just the same.
 
Good luck and stay safe.
