You need lots of leg strength for that so work on excercises for strengthening you leg first. Then practice your two point in halt, walk, trot, then canter. Your weight should be at your heels and also hold onto the mane of the horse to be balanced.
Hope you find this helpful!! 😁👍
I would first start by getting a solid leg strength so you can hold your self up. While getting started, you could hold on to the mane to help get balance. Also, I would sink your weight into your heel so it is easier to be more balanced. Hope this helped! 😊
