Due to an elbow issue full chaturangas or triceps / hands narrow push-ups are painful for me. So I modify, substitute, or skip. And if a workout relies on them, I think very carefully about whether or not the rest of the workout suits my needs. Sometimes it does, sometimes it doesn't. I don't stress about it. My body is my body, and everyone is much happier if I work with rather than against it.
There are so many forms of yoga that do not rely so much on the chaturanga. In general power, ashtanga, and other vinyasa schools flow or even hold the chaturanga more often than others.
Oh, yeah, jump throughs are another. I've finally decided my arms are short in relation to my torso and legs, so even when - if? - I master this move it won't be the beautiful float through people with relatively longer arms can do. Another thing I don't stress about.
