The user explained that his building has a small gym for residents — with four treadmills, three bikes and three stair/elliptical machines, plus an area for weight training.

A Reddit user asked others to weigh in on a question: Was he wrong to spend four hours a day on a treadmill in the gym in his apartment building?

"I am 99% sure it's aimed at me, as this morning about three hours in, a lady (I believe the building manager's assistant) informed" him of the rule, he wrote — "tapping me on the shoulder."

On the AITA subreddit, Redditors can reply to posts saying that the poster is "NTA" ("Not the A*****e), "YTA" ("You're the A*****e"), "NAH" ("No A*****e Here") or "ESH" ("Everyone Sucks Here").

The Reddit user defended his exercise routine, saying he uses his four hours a day on the treadmill for self-reflection and listening to podcasts.

"I fully agree and accept that in the very rare occasions all four treadmills are taken, I will step off in case people are coming by, seeing them all in use, and leaving," he wrote.
