I have a kid so I’m limited as to when I work out. I normally do it in the evening as a way of burning off excess energy, around 7 or 8 pm. I find it makes me mentally somewhat sleepy, though on the days I’ve had to get and do something hard in the morning I do find myself quite awake so I do toy with the idea of trying working out in the morning.

It's a good way to guarantee that your day can't get any fucking worse.
