I need help with posting?

you should take some lessons not only for your safety but the horses as well . when you post you need to make sure your on your correct diagonal being on the correct diagonal is When the leg on the outside goes forward you want to rise up. When it goes back you want to lower yourself back into the saddle. this is to create a smooth beat for both you and the horse . but when you rise you don't just throw your weight back into the saddle you need to use your leg muscles to lift and sit down
