ideas for how to enter this as exercise

Options
Hello~ I waitress part time 3 nights a week, I am literally on my feet (sometimes running ) for at least 5 hours while working. Since it is the summer, we have an outside. There are 3 steps up to the bar area and 3 steps outside.
Can I log this as exercise and if so what do I do? I know that I am working hard (exercise wise) cause the whole time I am sweating and beat at the end of the night.
Any help on this would be great!
Thanks!!!
