Don’t record someone without permission

Now that everyone carries a camera around 24/7, it can be far too easy to capture people and share it – whether they look silly while using an exercise machine incorrectly or are wearing a workout outfit you think may be inappropriate. Not only is this one of those things to never do at the gym, but you shouldn’t do it anywhere. “In your desire to have a good laugh with your friends at this person’s expense – or worse, on social media – you seriously violate gym rules and common decency,” says Steven McDaniels, director of fitness and recreation at Beacon College. “Instead of recording and making fun of them, why not make them feel a little bit more welcome be saying hello or offering assistance.”
Don’t talk too much

Add ‘be careful striking up a conversation with a stranger’ to your list of things to never do at the gym. “If the person is serious about his or her exercise program, he or she will be bothered by a lengthy conversation and try to sneak away from you to resume his or her workout,” says McDaniels. “Exercising already burns a lot of time, which people are usually short on. If you must chat, make it short, sweet, and to the point.”
Don’t leave a sweaty mess behind

“Not wiping off equipment that you just used and dripped sweat on is gross,” says trainer, Amanda Schaum. “Many gyms have wipes easily accessible so that you can wipe down sweaty machines immediately after use. It’s also unsanitary and rude to make other people remove your soaking wet towels.”
