As some may know, I have a problem with leaning forward, which makes me fall off from leaning so much. I read somewhere that if I lift my hands up more, that it will be easier to bring my shoulders back and lean. is this true? I'm really looking forward to finding out this Sunday and can't wait! I will post a video in the comments. =D
I do not believe that the answer to fixing a problem of leaning forward is raising your hands. In fact, I think that you are already off balance by leaning too far forward, and that raising your hands will further raise your center of gravity, throwing you even more off balance. Which is exactly the opposite of what you are trying to achieve: a low center of gravity.
I find that ground work in 20 meter circles helps me focus on balancing and sitting up tall. I often add in 1, 2, or 4 cavaletti poles (at 3, 6, 9, and 12 o'clock) as well to changes things up. Think "Hands low, sit back," and drive forward with hips. It feels like you are leaning back but it helps to have someone on the ground to tell you when your upper body is truly vertical.
I'm interested to hear with others have to say!
