Why? Push ups are a true “multi-tasking” exercise. When we think of a push up we all think of our arms and chest since that’s where we feel it most immediately. But when you do them correctly, you also work your shoulders, abs (a lot), gluteus maximus, quadriceps,and several of the stabilizing muscles in your back.
So what is a proper push up? Follow this link to the American Council on Exercise’s exercise library for all the details. And remember, if you can’t do a full push up right now, start with your knees on the mat and work your way up to the real deal.
