I published this over at WCF years ago and am reposting this here. I sometimes think about gym pet peeves while working out, so the topic is on my mind from time to time, along with some new ones.

1. Grunting so everyone can hear how much you are lifting.
2. Occupying a workout station by just sitting there, mesmerized by your phone while others may be waiting it.
3. Horrible smells from patrons.
4. Not re-racking your weights.
5. Singing aloud with the music you’re listening to through your headphones.
6. Bathrooms that wreak.
7. Having strangers working out next to you and chatting it up so much that you feel like you know every detail of how they spent last weekend.
8. Hogging multiple sets of dumbbells at the same time.
9. Being in a gym almost all by yourself, only to have someone walk in and use the exact machine or weights you were about to use.
10. Patrons who wear inappropriate workout clothing.

Now, some additions:

11. Social media bros who use the gym as a place for filming for Instagram posts.
12. Janitors/cleaning ladies who seem to not respect your space but clean all around you as you are working out.
13. Groups of high school kids who move around and occupy different parts of the gym to do their workouts/socializing, which basically prevents you from doing your intended workout.

Ok, that's all for now.  I'm sure there will be a few more to add from time to time.
