This is a difficult topic to articulate, as we are dealing with terminology that can mean different things for different people.
Either way, “Movement” as a sub-culture has certainly grown.
There are now facilities that focus specifically on this broad approach to training or “practicing” and some of them are completely outside of the “fitness” or exercise circles.
It has gone beyond the innovators, and is certainly being embraced by early adopters in the broader culture.
However, from a market perspective, as Geoffrey Moore discusses in his book “Crossing the Chasm,” the challenge is still ahead.
The difficulty for “Movement” training to move beyond early adopters (if it does – and, it doesn’t have to in order to flourish) is that it needs to cross the chasm to the early majority. Because the early majority generally don’t look to the early adopters as points of reference (and they need a point of reference, or social proof), it is interesting to see where the relevant drive to this new market segment may come from.
The seeds for this are in fact there – “Movement” has become a way of training or practicing for athletes outside of the Movement culture itself – surfers, MMA and UFC fighters and more. TV shows such as Ninja Warrior have been embraced by the Early Majority (these have heavy ties to some aspects of “Movement” training).
These are valid references for the early majority, yet there are other hurdles (perceived difficulty is perhaps one)
It is an interesting landscape and as always, our overall culture and our set of beliefs (not science, logic or reason) will dictate whether it bridges over. If it does, as usual, there will be significantly more upside to the industry leaders and “firsts.”
