to learn to be aware of the distance you move during a roll and to control it roll without walking. This means you take a few minutes (10) to roll without walking. You stand and roll and come back to a standing position without any steps. Move like this from spot to spot and relax using your breath to guide you. After a while you will automatically know and be more aware of how much you move in a roll and in which position you will naturally come to from the roll. This is important and will make your rolls more self aware in the ending and start as well since all the parts of the chain effect it.
Things to notice:
how are you feet placed in the start?
Where does the roll start in your body?
Where do your eyes look at the beginning and during the roll?
Are you changing your breath as you roll (hint: breathe like you do all the time)
Are you placing hard on soft and vice versa?
Are you doing something that is yours or mimicking?
