Take lessons with a trainer.
Getting a horse properly collected for their event (Ex: Arabian western pleasure will look different from Quarter Horse western pleasure) takes seat and legs moreso than rein. And timing is so very important. If you release pressure too late or too soon, you've taught your horse nothing and/or bad habits.
We cannot teach you timing
over the internet. You need someone in-person giving you instant feedback on what you are doing wrong or what you are doing right.
