Re: Breakfalls can be a problem!
One of my sempai showed me a way to practice landing properly without the added problems of "letting yourself fall" rather than "throwing yourself into a fall":
get on your hands and knees. Put one arm across your body,reaching under your opposite arm. Have a partner take your hand-they will probably need to crouch or bend. They stand up straight, your arm goes up and the rest of you follows! This has been good for me because it gives me actual "air time" rather than trying to take a roll in mid-air & then trying to land right.
Now I just need to get people to do this with me more often!
