Use the same movements when round penning your horse bit up as you did when round penning freely. This step saves you a lot of time and energy by allowing the horse to figure out how to move with pressure & collect, in a relaxed state. Every horse is an individual. Remember to take your time, evaluate the horses condition and give your horse time to figure out what you are teaching them.
Some different way's to bit up your horse:
Halter & saddle
Side pull & surcingle
Snaffle & Saddle
Curb bit & saddle
Saddle/Surcingle and Bridle your horse.
Saddle: Thread the reins under the stirrup leathers or through the stirrups, and tie in a square knot behind the cantle of the saddle. Short reins may require just looping over saddle horn or an extension so the horse can get relief when they are collected properly.
Surcingle: Usually used to start young horses so as to not damage to saddle while they learn to take pressure. Have many options to tie reins to or other aids.
Signs of relaxation are:
As you progress, do less bitting up, and more riding.
BE CONSISTENT- persistence pays off
