Stacey Westfall Bridleless Riding How Does She Do That? Best video for bridleless riding and I'm training my TN Walker brideless this August (first gaited horse to go bridleless! :) . . .)
Ok, start by making sure your horse stops, slows down, speeds up, and turns REALLY WELL! Especially the stopping. Get it to where you only use one hand on the rein in the dead center raised just above your horse's neck. Only move it an inch to turn each way. Then start desenseitizing your horse to a gentle waving of you legs to match every stride your horse is taking. This will help you in every single thing you do bridleless.
Stopping. Your horse should stop immediately when the waving of your legs stops and your legs are pulled off her sides. Back this up with a "Woah!" command in a low voice and lean slightly back.
Turning to the left. Your horse is taught to move away from pressure so . . . when you want to turn, the waving of your right leg should increase and the waving of your left led should be more suttle but IT SHOULDN"T STOP. You are essentially opening and closing the door for your horse.
Turning to the right. Opposite of the left.
Slowing down. Wave slower.
Speeding up. Wave faster.
The Lope. To transition from the walk or trot to the lope, Get to the point in which your horse only lope to the kiss. The kiss is the que to lope off. Leaning forward, your horse should be aware that you are thinking about speeding up. Set her up: to lope to the left, your left leg should wave slightly more towards the cinch (aligns your horse's shoulder) and your right leg should wave more back.
-then set him/her up
Backing up. Train your horse so that when you ask him/her to walk forward then stop them and immediately wave really fast NOT HARD in the neutral middle postion, that they should back up.
Training bridleless takes years and CONSISTANCY is the KEY.
Make sure your horse is excellent with the basic, walk, trot, lope, slow down, speed up, stop, and back.
Always do these with a bridle on.
Do the cloverleaf pattern.
When your horse responds to your leg pressure well, tie your reins up on your saddle horn and try not to use them unless in a critical situation.
Stacey Westfall's video explains what I can't. Hope this helps! :)
