In this tutorial, we learn how to build chest muscles through chair push-ups. To begin, you will need to set up three chairs in a pyramid shape that will fit your body laying down. To begin, place both of your feet on one chair and then push each of your hands laying on a chair. After this, do as many push ups as you can. If you want a more challenging work out, you can wear a backpack that is filled with weights. You can also stay at the bottom for a couple seconds while you are doing the push ups to prevent yourself from having momentum and going back up. By using these exercises, you can have bigger chest muscles in no time!
