I don't understand what exactly steroids do, but my muscles all felt lubricated and luscious and moved well while I was on the prednisone. And a bunch of the hitches and sticky muscles and joints? Just slid, released, let go. I can squat all the way down now! my shoulder and my hand from where I broke my hand NYE 2016, all that shit let go! my lower back and my hip let go!

They're anti-inflammatory, with a capital double I! So basically, the stuff making you feel stiff and sticky and so on? Mostly related to inflammation over a long period of time.
