Guys it's not impossible, just a bit harsh... you know how Metal Bat gets stronger cuz of his fighting spirit? that's will power, if you stick to your guns with an unbreakable will and endure further than you should be able to, you'll break your limits (we are all limited by pain, Saitama is just WAY more strong willed than anyone, probably the strongest Green Lantern if he got a ring)
