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?
What I mean is that being able to perform pushups will help you perform a planche, sure, but there are progressions in the planche learning process that are easier than pushups and once you complete them you should have the strength to perform push ups if you so wish. But spending your time learning how to perform the perfect pushup isn’t really that worthwhile of an endeavor.
