For the theme of "fitness," I was still thinking about the various glyphs and symbols I worked with last week, and wanted to do some basic icons related to fitness. I have a very young baby (almost 7 weeks!) so I'm not able to think much beyond the essential functions for life. So I came up with some very straightforward advice on health: get enough sleep, get some exercise, eat a balanced diet, and drink plenty of water. I made little "icons" for each of these.
For the colors, I used the "Doctor" colors from the synergy project, which I hadn't used yet. This entry came in very near the bottom of the contest. My favorite was this nice usage of running shoe treads.
