Here’s how to do a proper push-up:1. Keep your arms at 45 degrees. You do not want them flat-out horizontal, which could lead to shoulder injuries and also won’t work your chest as well. 2. Flat back. Make sure that during your push-up, your entire body goes down at once — you don’t want your chest or your hips to lead. Keep yourself level and even. 3. Knees, if needed. If a traditional push-up is too difficult, then start on your knees. When dropping to your knees, make sure you start in a nice plank position, then drop your knees right where you are.
