Impact wrench is the quickest way. You rarely have to hold anything.
You can thread a couple bolts into the pulley holes and be creative with a pry bar against those and the ground also to hold it in place while going after the crank bolt by hand.
Do this only if you are wanting problems that are very avoidable with all the proper tools and

He's not talking about pulling the balancer, but how to keep it from rotating.
I pull one plug, stuff about 3 feet of 3/8" nylon rope into the cylinder and that will keep it from rotating. Just tie a knot on one end to keep you from stuffing all the rope in.
