After immigrating to the U.S.A. in the early 1980s as a political refugee, I was looking for a way to make a living from my sports-science know-how. So I was looking at publications on various aspects of sports training and p.e., among them martial arts’ magazines. Especially in those martial arts’ magazines, I noticed a need for good instruction on practically everything. I decided to sell my know-how on flexibility, because it’s so easy to advertise.
Think, how would you advertise, let’s say, the best method to improve a high jump and a reach jump? It’s difficult to show a photo of a dynamic movement that convinces people. But with flexibility it is very easy: a photo of a split between chairs proves a point: the great range of motion combined with considerable strength. But I did not use a photo of a front-back split — I used a photo of a straddle split because, unlike the front-back split, it plays on a human viewer’s “monkey mind.” To see why it does it, read my new post at https://www.stadion.com/high-kicks-and-splits-monkey-mind-and-advertising/
