Start for the beginning. Master it at the walk, then Trot, then canter. If you skip a step you'll more than likely do damage to the horse or his training program.
Every horse is different (like when you shake hands with people they're all different) so you will have to adjust with every horse you ride. Don't be afraid to take contact but don't pull. Think of riding your inside leg to outside hand, your outside hand is responsible for the speed and weight (contact) with the horse, this hand should always have some weight even if it is light with the horse. Your inside hand or used for bend and direction. Don't ever completely let go of the contact when you're working him (unless you're letting him stretch and walk) but adjust to a lighter contact when your horse gives or lowers their head as they relax
Pretend you are holding s baby's hand. You Wana b light. But firm with what u are asking. Don't sea saw. To yget a "frame". But rather. Use your le to bring your horse up to you with light half halts. Aswell
Imagine that there isn't a bridle and all you have is a bit and reins.. try keep the bit from falling out... that's what my trainer said
