I tried

Is there a more pathetic phrase? But I did. I ran three on Monday evening, and then circumstances and laziness caused my lonely gym bag to stay sitting in my car, unused and unloved, until tonight. 

But it just wasn't to be. I got a mile and a half in on the treadmill and that sharp pain in my foot came along and wouldn't let go. So I shifted to the stairs where I did ten minutes and then tried the treadmill again. I loosened my shoe laces and went slow but it just wasn't happening. 

So now I'm just soaking in the hot tub and finishing up my audio book on checklists and how they can improve surgery outcomes. Because it's Friday night, bitchez.
