Does the answer to this question differ depending on which Superman we are talking about??
Don't know if this has ever been discussed here, but I've always wondered about that.
Similar situation is having the Hulk do it. Except with Hulk, the angrier he gets, the more powerful and more durable he is. So to Hulk, this becomes an infinite loop.
Superman, on the other hand, doesn't have the option of instantly gaining additional strength and durability for whatever reason. Superman seems to have a set upper-limit on his strength, I think. So this becomes a more interesting discussion.
