Is mirror in a gym given for self obsession?

It can be...but it can also be used to check your technique, and I know that some people are perfectionists when it comes to using the right technique.

Yes. It drives me crazy at the guys who will work out for 2 minutes the flex and make selfies for 10 minutes. Geez.

No. It's so you could see how awesome you look. ☺️
