I'm up on my second month of practicing aikido and its just now that when we've started with a couple of exercises and techniques that involve forward rolling that i feel i got a good hang of it.
Kaitennage when done really slowly, is a good way to practice
forward rolls, especially since you basically stand with your nose
on the mat. All you do is put your arm, shaped as a wheel, with blade of your hand on the mat by your side and slowly roll over.
At first it really does have a please-come-help-me feeling, but the more you do it, the more secure you get, and the more natural the rolls come. So no hurries. You'll roll like a pro in no time
