What are your Gym Pet Peeves

As I've spent more and more time in a commercial gym lately, I've been reminded of some of the lapses in gym etiquette that really annoy me. I've listed a few below but looking to hear yours.

1. Not putting weights back where you got them - In other words, keep the dumbbells in pairs. If you take plates from one rack to use at another, put them back on the original rack when done. Don't leave the plates on the bar when you're done. Quit being so lazy and put things back where they belong.

2. Quit trying to invent new exercises by using equipment in ways it' wasn't meant to be - I don't know why this annoys me but it does. People who do completely unconventional exercises that could be accomplished in other ways for seemingly no other reason than to show they are "creative". As an example, at my gym on the multi-stack machines, all of the lat pull down bars are connected to the cable with rings that are screwed shut (as opposed to the spring loaded releases on the other parts of the station). The last three times I've been there now I've found someone unscrewed the ring, took the bar off and replaced it with a single handle or the W shaped handle (also steeling the spring release from the other cable). WTF??? At least if you're going to do that, put it back together when you're done!!

3. Using a bunch of add-on weights rather than just adding another plate on weight stack machines - Saw a guy the other day stack 3 of the 5lb add-on intermediate weights to the weight stack on a curl machine. The plates on the machine weigh 10lbs each so what gives? Each machine only has one of these weights so he had to steal them from 2 others. And of course he didn't put a single one back where it came from. UGH.

So what is it at your gym that annoys you?
