On automatic cars I use a large screwdriver through one of the holes in the flexplate to block it from moving, the screwdriver will rest against the block were it's machined flat. Others have had luck using a big pair of Vise-Grips locked onto the flexplate.
Another trick is to use a 15/16" socket on the balancer bolt and a long breaker bar (or slide a section of pipe over a shorter one) and rest it against the frame rail. Bump the starter and your bolt will loosen.
Both of these methods assume the engine is still in the car, always loosen it up before engine removal unless you have an air impact gun.
