> You shouldn't be surprised when none of these things "work" -- do you even understand why they should?
Understanding is not required for many things. And in fact, the thing does work!
As an example, I do not actually understand why lifting makes me stronger. Why do muscles respond to increased resistance with more strength? Certainly my ankle ligaments didn't respond to injury with more strength. Well, I don't care and it doesn't matter. It will still work.
Maybe you'll get lucky. Or maybe, you'll wish you took the time to understand should you blow a disc in your spine. Is it possible that that you'd learn a bit more about the difference between bodyweight exercises and more than bodyweight exercises, and the requisite amount of care to do the two sustainably long term without incurring risks of debilitating injury?
But in my case I just paid a guy to tell me what to do until it became automatic habit.
