I've decided to incorporate some daily push ups into my routine, as my fitness New Year's resolution.
In order for me to be able to stick with it, there has to be only ONE exercise. I cannot fall prey (as I have in previous years) to the trap of "oh, that was easy, what else can I do?" and then adding more exercises, and then having a tired or busy day were I don't do them all, and then giving up completely. (Welcome to my world ;)
I decided on push ups because they can really work your core, in addition to your arms and chest. If I'm only picking one thing, it has to accomplish as much as it can. I've also discovered that there's more abdominal involvement if you place your hands further above your head.
I'll do twenty every morning while my coffee is brewing, and I'm starting with wall push ups, because on the floor I can do maybe three, tops. I'll let you know when I move up to twenty on the floor ;)
