I heard about this program from the Tim Ferris podcast. After watching the first video I was skeptical until I move my office chair and tried the crab and ape. I thought I still had a respectable level of flexibility for a 32 year old but damn it was hard to hold let alone walk in those positions. That challenge alone made me smile that I've joined! I look forward to the challenges ahead and will look to post progressions as I go along.
