I find that so many days I am so stoked to exercise after work when I am at work. However, by the time I've spent the whole day convincing teens that logarithms are something they need to know and then graded their papers and tutored for free after school, made dinner and cleaned it up, I am not always motivated to work out. I found this giant list of reasons why I should workout.
So far, reading through this list has been motivation enough to help me get motivated to do at least a little bit of exercise. Enjoy!
