I want you to pick 4, 6, or 8 strides to work with and stick with that same number the whole time you do this in both directions. So if you pick 6, use only six. Also use the higher number if your horse is greener and work your way down to the lower ones as you master the exercise at each number. So when you have it good at 8, go down to 6 and so on.
The first stage is to work on walk to halt at the stride number you have selected. So from halt you would count 1-2-3-4-5-6-7-8 halt again and repeat on whatever pattern you have chosen to ride. I'm not going to tell you what this will do because I want you to discover it and report back in the comments what you found. All I will say is to do it until it is relaxed and as effortless as possible. Make mental notes of how it feels in the beginning attempts, and then notice changes until it's easy and relaxed. Make sure and stay in the halt on a slack but not loose rein for at least 5 seconds and that the horse will maintain the halt on the slack rein. If he doesn't, remind him of your request patiently until he does.
The number up repetitions is not as important as the moment you get relaxation and the feeling of little or no effort. When you get that, Let the horse stand and relax on a loose rein or free walk on a loose rein for at least 30 seconds before resuming and or changing directions. This can be progressed to trot to walk when it is good in walk to halt. This exercise can also be introduced at liberty and online first and I encourage this whenever introducing a new exercise or pattern before doing it mounted.
Pay attention to little changes good or bad leading up to it being good. If your horse is stopping crooked or sideways from where you planned to halt, Guide them calmly back to the spot you meant to stop. Let me know what you discovered in the comments!
