I work out in my underwear because it makes me feel sexy. A sports bra and briefs make me feel like those be-hot-pantsed fitness instructors with cut lines from here to there. I don’t have cut lines anywhere but that doesn’t matter. I can see my muscles tensing and contracting, shifting and moving under my skin (and adipose tissue) to make the movements I do.
I feel like super woman when I see that. I have muscles and they do things! A fact I knew intellectually before I started working out at home in my underwear but now I can see it happening for real I see all the little movements it takes just to do a press up or a squat ( I also work out in front of a mirror) and I can revel in the miracle of all the little forces coming together to make it so that I am able to do these things.
In the gym I could feel my muscles moving but I couldn’t see them and so it did not impact upon me in the same visceral way. I did not have that punch to the gut realisation that I have a body and it is good. That my DOES things many things which I do not actively control. As a result I am more grateful for it than I ever have been.
