I liked the simplicity of ritchielee’s chart. What I didn’t like was the black black background. I found it hard to read the colored lines and text. Especially as one’s eyes age, a white background with dark colors is easiest to read.

It looks pretty striking on a computer monitor. He’s just used yoga, running, and walking; which are probably amoungst the most common forms of exercise available to many. Although it would be more compact if he used half a pizza as in your reworked chart, and as per comments above, may leave some non-chart-savvy people scratching their heads. But hey…that’s exercise.
