크리스 케일리와 인터뷰

Chris Keighley helps me muscle up the strength to understand challenge. We discuss its rewards, hazards, and how it can be a powerful tool for personal growth from day one. He shares stories from behind the scenes of the 1,000 Muscle-Up Challenge, and talks about finding challenge in more mundane activities, like building a tire tower at the Gerlev International Gathering.
