If you don't have an allen head socket & breaker bar, you can also use a punch sized small enough to reach to the bottom of the allen recess without damaging the hex part where the wrench grabs. Whack that sucker as hard as you dare to not bend/break the punch, and you will often break them loose with just the L-shaped wrenches, if that is all you have.
The key is to turn and keep steady pressure on the hex wrench or socket while you smack it with the hammer. Dan's right--sometimes it's like magic the way frozen allen head bolts come loose after only a couple whacks.
