Take a long lead rope, slide it down to your horses back pastern and pull it up. Stand by his shoulder, that way your out of the way if he has a kicking fit. My filly went through a couple stages, one where she decided she was going to fight picking up her back feet. I did this until she quit fighting, then put it down. Picked it up again, and she was fine. No issue since. She also tried the laying down crap on the front feet. I had her in the arena and as soon as she laid down, I moved and smacked her on the butt with the rope. Sent her around a few times and she hasn't tried it since.
