On Tuesday (my rest day) I had a bad day at work and needed to clear my head, so I went for a swim. I didn't do much, just 5 laps, but it helped with the head clearing and it felt really good to be active rather than behind a desk all day. Plus I get zero upper body workout, so it was nice to feel those shoulders and arms doing some work.
I was wondering if anyone does some kind of exercise on rest days too or takes "rest" more literally?
