Legendary Squaresoft weapons... the ultimate weight lifting program. You don't need a gym.. you don't need the P90X program. Just get one Final Fantasy sword, made of real metal and carry it around with you everywhere... You will be built like a truck in no time.
Ironically I am now in the process of going through the P90X program. But yea, if that Buster Sword were the real deal it'd definitely be a workout all on its own xD
