As a bloke, but a crap one, I'll put in another good word for the off road school. They taught me to be much less concerned about the weight of the bike, and to get off to push it around. I'd also suggest getting a light bike, ideally one you don't care much about, maybe a trail bike. Ride it to a standstill, push it around, mount and dismount via the footpeg.... Once you're happy doing it with a little bike, it turns out you can do the same things with a big one.
