Every time I see a video of someone doing push-ups, there's always someone in the comments saying about how the form is bad. I was always told my form was bad, but was never told what to do to improve it. Are push-ups just some Emperor's New Clothes kind of thing where nobody knows how to do one, but everyone needs to pretend to know so they don't seem like un-fit idiots?
Counterpoint: Do not skip push ups, they are an excellent exercise and can be scaled to pretty much every level. A planche progression isn't bad thing to learn, but static strenght and dynamic strength are different things.
