5 K Midnight Run + Upper Body Park Workout

When I came home from a 90-minute corporate seminar, I was so sleepy, but my body wanted some physical activity to reset the exhausted mind, so I went out for a 5 K jog around a 2.5 K loop near my house. I wrapped up the short jog with park workout consisting of 4 sets of 45-second swing push-ups, and 45-second lying flexed arm hang with a short rest between exercises. In about 50 minutes I was totally refreshed, and my mind was completely reset.
