When you feel stuck at work, get a move on

If you're feeling stuck on a section of your report or just feeling tired in general, it's most likely that your body is not getting enough exercise.

Exercising raises your heart rate and increases blood flow to the brain. It also increases your cognition - which would be greatly beneficial to you and your task. It doesn't have to be a hard exercise, you could take a 15 minute walk outside just to refresh your mind and let yourself take a breather.
