It's not about the fancy gyms free on campus or one off runs, it's that on the weekend physical activity is a normal part of my work and on the weekday it is antithetical to my work.
I, and several others, have expressed a desire to leave tech over this issue. We are active fit people who TRY to workout and eat right, but our work grinds our willingness out of us while demanding large numbers of hours being physically inactive.
