The more I think about it, the more I get to like the pushup (as I've said before). It is the fundamental exercise that everyone should be doing, not just for the upper body, but for everything - posture, core, the lot. You need solid hips / glutes and upper back/traps. You need to be able to hold the plank position before you can do the exercise.
Yet rarely do you see a decent pushup. People move too fast, but don't move enough. They rarely hold the plank.
I sometimes think that in terms of basic strength, a pushup and a proper squat (or a wall sit) would be enough for most people.
Anyway, Greg Everett has a superb post today on the pushup and the need to develop it as a basic exercise:

There's a lot of confusion around the basic pushup because there are a lot of different opinions about how to do it. For example, I don't agree with his 45 degree angle recommendation for hand/arm positioning because I like the elbows in tighter to the ribs, which puts less strain on the joints and allows greater force production potential.
That said, there are different techniques that are most appropriate for certain goals. So, the best pushup for one person might not be the best pushup for another. Some technique qualities will remain constant, yes, but others may vary based on goals.
Regardless, just doing pushups is an impressive first step, and for most people, these details don't matter all that much. Us geeks need to get a life sometimes!
I'd actually agree on the keeping the elbows in a bit tighter.
By the way, tonight inspired by your article I decided to do 5 minutes in the pushup plank position. Tough but I made it.
Not much else to do for chest in these situations ... but I'm not complaining. I've done regular ones, clap pushups, backpack weighted pushups, weighted with a clap, slow motion ones - you name it. I'm slightly sore at this moment from some super slow, non weighted ones yesterday.
The pushup is simple in principle and powerful in effect. Can't beat it.
