A fun learning method to learning your balance is to stand on one leg and look around with your eyes. Bend this way and that way, twist and go up and down and counter the mass shift using your tension and your free limbs and head. For example if you are looking down to pick up a dropped coin than you can release one leg up to counter and as a fulcrum back up. Another example is using your hands to the sides to balance out the twisting of the trunk and hips.
