I don't work out weekends, so no comment there. That being said: Mondays are the worst and it gets better until fridays, which are the best. After work is the worst time (4:30pm-7pm). It gets better after that, slowly. Mornings are the way to go if you can manage it, earlier the better. I have limited experience during work hours. The Monday after new years is going to be hilarious. I'm probably going to work out Monday morning, then go at 5:30pm just to see the shitshow.
