Yes, I like to exercise outdoors after work. Much more pleasant when the sun is up. Especially if I'm cycling - even with multiple blinking lights, I don't feel particularly visible to drivers.

That said, with the shortest day's light ending before 5pm, even shifting to near 6pm doesn't really help - I'm at the office to 5-ish and if I'm lucky I can be ready to run/bike/whatever by 5:45, so its going dark mid-workout at best.

And I'm up at 5am, so in the dark most of the year. Ditching DST would make it daylight in mid-summer, but I do really enjoy having daylight past 8pm, so I can sit outside and read.
