There is a whole of genre of “you tube’ like channels on the net that feature workouts and exercises with absolutely no context. No experts to provide expertise. This may not matter to you, but it does matter to me. All this is just “stuff” without any frame of reference; no why, just a whole lot of what, sometimes a little on how and they would lead you to think the who is everyone. I may be old fashioned but I want more information, some simple things like: Tell me what you know? Where did you learn it? How have you used it? Did it work? Why? Did it fail? Why? Just more exercises and drills by themselves are not the answer. They must fit your situation with your athletes and in the context of your training system.
