I work nine floors (or 180 steps) up in my building. I moved here in June from a building that you could only access the stairs to the ground floor in an emergency (appalling building design IMHO, which forced people take lifts from even the second floor - the first had a flight to the ground floor exclusively for their use, used by very few however).
Now having access to stairs again, I have been using them in the down direction on most occasions. I’ve now started using them more often in the up direction too (cheaper than a gym). So far today 340 stairs up/520 steps down. I’m curious what difference a few weeks of this will make.
