Finally getting around to commenting on this.
While I completely agree that movement is the optimal goal, I think youre going off in a different direction than responding to the message I was trying to convey.
I agree that moving from open to closed kinetic chain movements should be more engaging and interesting due to the complexity of the movements. However, when one finds closed chain exercises boring and mundane, where does the progression go from there? When those types of movements are boring and uninteresting, its not an exercise issue (ex: db press, etc) and more of a mentality issue.
While I think some of the ideas in the video are really useful, some of it is "hippie-ish". Training movements is important, but theres a point where many of those movements arent correlated to any activity besides just doing that movement.
Boredom isn't related to exercises, that's a cognitive issue and no matter what exercises are recommended, they'll all become boring pretty rapidly.
