5. Dropping weights
If you’re a weight dropper, I hate you. First, if you have to drop the weights, you’re probably lifting too much to begin with (or you need a spotter). Also, it’s an annoying habit. Also, it can damage dumbbells and cause them to break. Do you want a dumbbell falling apart on you when you’re doing dumbbell chest presses? I didn’t think so.
6. Grunting excessively
A little grunting, fine. Crazy, I’m-about-to-orgasm grunts? Just know that everyone at the gym is laughing at you and rolling their eyes.
7. Forgetting your shower shoes
Because athlete’s foot isn’t limited to high school boys' locker rooms.
8. Forgetting your headphones
There’s no better excuse not to talk to anyone than to pretend you don’t hear them.
