a gym? what's that?

I've not been working out regularly since I got sick last March. I've pretty much flushed all the progress I made away. Now that I'm losing weight, I'll be losing muscle too. If I want that trend to stop, I need to act yesterday. I've been naturally strong for most of my adult life, I don't want to be a skinny weakling. So, I must make it a poit to get back into a gym routine.
