Going for a bike ride works well for me. I know the roads around my house & office quite well, so I can be on semi-autopilot, riding with just enough focus on my surroundings that my backbrain can still mull over a problem. Or, I can ride hard and grind out a stressful afternoon. Either way, it's a good time for inspiration to strike. (Weightlifting is great, too.) My office is big on darts, but that doesn't get the blood flowing in the same way as ping pong or cycling. :)
