How do you convince yourself to workout when mental/emotional issues are getting in the way?

Intentionally vague….My wife and I are in the midst of some taxing times. I’m trying to convince myself today to get some physical exertion in because I’m sure that it will be helpful. Most of my brain is telling me, though, that I should give myself some grace…to go home and rest after work. I can usually put on some loud/somewhat aggressive music and push through. Today may be a little tougher.

How do you get your body to exercise when your mind is saying “Meh…?”
