Get somebody fat and take them flying, and do a bunch of takeoffs and landings, that will help.
Can you be a bit more specific please Jeff - Gayle does not have fat so I have kicked her out of the PAX seat for a while. I did find one very fat candidate but thought I might have trouble fitting in besides him! I think I now have a nicely rounded fat person (abit like myself). Pictures would help a lot.

cheers
