Gyms are like different countries which many people choose never to visit. However, I have a passport and a permanent visa so I'm a regular visitor. I almost belong to the gym sub-culture. I say almost because I'm a Square Peg.
Here's a list of my pet peeves at the gym. I'm sure I'm not the only one bothered by them, but overall these things seem to be generally accepted as normal in the gym sub-culture.
1. The music. Selected by a handful of gym folk, it is a nice blend of jungle music (dance and hip hop), and...more jungle music. I need a metal and rock soundtrack. I could chose the music and share it with everyone else, except for the fact none of the songs I like are available on the "jukebox". My iPod shuffle saves me.
2. The dropping of weights. If people can't put the weight down, then I'd suggest it's too heavy. I'm sure this is not attention seeking behaviour but it does attract attention.
3.Water bottles. It is not far to walk to the bubbler for a drink between sets or exercises, but for many people it is apparently too far. Irony alert.
4. Sitting on equipment but not actually using it. I reckon it's possible to leave your phone in your bag for an hour. It's also possible to have a conversation with your friends whilst not sitting on a particular machine.
5. Excessive grunting. I know it's hard work and it's painful, but some gym folk are Maria Sharapovas. Not seeking attention, but getting it.
6. Racking weights. There are signs everywhere, but it's evidently too hard to put away the weights they use when they've finished.
7. The floor is better than the storage cubes. There are empty spaces for bags to be stowed off the floor, but it's a bit difficult to lift the bag and place it so people just dump them on the floor.
8. Share your conversations with everyone. People who talk really loudly; thus ensuring the whole gym can hear every word.
Two final thoughts: I wonder how many other people even notice these things, and secondly I wonder how many people have to fight to overcome the self consciousness I still feel when I'm working out. Maybe, it's just me.
