If anyone's thinking of doing this on your own, be careful.

Don't start out kneeling. Start out sitting/lying down, just rolling back and forth, then into backrolls. Then you can try kneeling.

Same for breakfalls -- start out just lying down and getting used to slapping the hard surface without banging your joints on it -- then go to backfalls from sitting, squatting, standing, then try controlled forward throws with a partner (I'd never throw myself into a forward breakfall on concrete, or even wood).
