lol ive stumbled and regained balance loads of times and at first when i couldn't even walk ive fallen onto my bed loads of times too as i've been practising in my room :D
that methods old...and hard, very hard on slippery surfaces XDhaven't seen a roll down/up on bocks yet(where you lie down backwards then do a roll to kneeling...and the opposite)
