Push-ups can be a great full body exercise that is easy for anyone to perform anywhere. All you need is a floor. You may think of the push-up as being predominantly an arm strengthening exercise (pecs and triceps), but if you perform it properly, you will also provide your core, and scapular stabilizers (serratus anterior) a great workout as well. If you are not using these muscles and properly aligning your body, you may be placing excess sheering, compressive, or torsional loads to the shoulder or spine. Below, Tara and Anya outline some key points to think about the next time you do a push up and provide a great example of good technique vs. poor technique with the push-up exercise.
