I’m a technique guy, and I try to be a fitness guy. I spent a lot of time doing pushups incorrectly, and I frequently find myself looking at folks on tests and in classes doing either: a.) terrible pushups due to not going through anything close to a proper range of motion (aka ‘elbow twitches’) or b.) giving maximum effort to doing pushups with a form that will likely injure them. I am convinced that a recurring shoulder injury I have is directly related to me doing thousands of enthusiastic repetitions of poor form pushups. I’ve tried to clean up my act, and I think this video (not by me) does a good job of explaining proper form for the basic pushup. You probably can’t do as many of them as you think you can.
