In search of the climbing phenom\'s formula for success, part 2 in the 4-part series stops at the New River Gorge national park in the US. Once again on Alex\'s menu _ the toughest climbing routes of the world: ?When push comes to shove there\'s only one reason for personal failure,? says Alex self-critically: ?It\'s not because it was too warm, or because your fingers were taped, you only fail because you're too weak!?. In part 2 he defies physics in 8a+ routes like The Racist or 9a routes like Superpod. ?If you\?re able to climb 9a routes smooth and relaxed, you might be able to climb 9b and c routes fairly easy,? says Alex. Sounds logical? Watch, as Alex makes sense of it all.
