To eliminate survivor bias just buy programs that have return policies like GMB and GymnasticBodies. A return policy says the person is so confident in everybody's success that they will even give you the money back.That's why I say show me the 'average' person, not the guy that grew up doing gymnastics. (Plus, their fascination with extreme shoulder mobility seemed off.)
And worst thing happens? You return it.
