Physical exercise for me is primarily a way to make my body produce drugs, to be in a better mood and sleep better. All the other benefits are icing on the cake.
One small caveat is that I must already be in a somewhat decent state to do physical activities. Sometimes I'm just too "mentally tired" to even get myself to exercise - it would be great to have a tool to get over the hump in moments like this.
In my case, I always throw my trash in sports clothes.
I need to take trash out. I also need to change clothes when I go out, because I work remote. So just choosing sport clothing instead of something else is very frictionless.
Once the trash is thrown, I'm out not he street, with my sport shoes on. I just need to start running at that point.
Comparatively, just "purposely going for a run" feels like climbing a mountain.
