they also have something called lockjaw. when they clamp down on something they arent letting go unless they want to.
Actually the comman weight for a purebred pitbull is between 35-55 pounds, while the original APBT were 20-40 pounds. Almost all of the muscle bound pits you see weighing 80-110 pounds have been cross-bred with other breeds.

Also, there is no such thing as "lockjaw". Pitbulls have very strong jaw muscles, but DO NOT lock in any way.
