A personal trainer has revealed the one bad gym habit that drives staff and customers crazy.

Angie Crowfoot (@angiecrowfoot_pt) a personal trainer in Sydney’s Shire, told nine.com.au there are three unwritten rules of working out that everyone in the gym should know about.

When people break these rules, it can disrupt the safe and supportive environment gym trainers and owners work so hard to create.

Crowfoot says the overarching rule is to be considerate to others, but one rule in particular is the most important to remember.

“Always stack your weights back,” she said.

“Something, as a trainer, we really don’t appreciate is when people don’t put their weights back.

“If someone has lifted 180kg and then they leave that there for the next person … you’ve gotta be considerate.

“There could be elderly people in the gym, there’s no way they can lift that. Things like that are really inconsiderate.” 

The other unspoken rules revolve around being a pilote and considerate person, and remembering the gym is for everyone.

“If someone is training next to you, and you both need to use the same machine, generally people should let you work in between (each set), share the machine!” Crowfoot says.

“Just be polite in the gym, to everyone you’re speaking to, and also wipe down the equipment when you use it.”

When it comes to workout classes like yoga or pilates, Katie Drury, studio manager at Club Pilates in Perth, says similar rules apply.

“One of the most important rules is to arrive to your class on time,” Drury told nine.com.au.

“Be prepared to start on time, especially with Pilates, there’s a bit of setup involved.

“You just want to make sure that you’re not disrupting the rest of the class [by being late] and come prepared.”

Drury says similar rules about wiping down your equipment apply.

“Generally, the instructor will come around and pop a wipe on the end of your reformer,” she explains.

“Just wipe down all of the equipment that you’ve used.”

As social media gym influencers become more and more popular, new rules are being formed in gym culture, Crowfoot says.

If you wish to film in the gym, you must ask for consent from anyone who may be caught in the back of your video.

“There are different legalities for different gyms, commerical gyms are more strict on your filming,” the PT told nine.com.au.

“The general rule is you’ve always got to tell the person, ‘I’m about to film, do you mind being in the background?'”

She said the gym is a safe space for everybody, and offered a peice of advice for anyone looking to step inside for the first time. 

“People aren’t as scary as they think. No one is actually judging you [in the gym], they are focusing on themselves,” Crowfoot said.

“I could do a cartwheel in the middle of the gym and no one would question me.”

She adds that “there are so many people in the gym that are willing to help you” and personal trainers are always a good option if you are starting out from scratch.
