I participated in this seminar with 10,500 other attendees. It was challenging in a number of ways (the work, the 15 hours days, the (deliberately) chilly room), *and* I’m glad I attended.
Themes: personal development and overcoming limiting beliefs, business, and health. And we walked across hot coals—much more of a mental exercise of overcoming fear than something that could cause serious harm. We went through a movement exercise with Wim Hof (the Ice Man), and then the breathing exercise, which is described here: http://www.icemanwimhof.com/wim-hof-exercises
