Newbies are newcomers at the gym. They follow the instructor like lost puppies. If the instructor is busy, they follow anyone who looks like they know what they're doing, which often includes ripped guys. A few days into their workout, these newbies are introduced to a sad fact that exercising leads to body aches. And then, they begin to make their presence felt in the gym by cribbing and whining nonstop.
The know-it-all are gymmers who have either worked out at a gym before and/or have extensively researched on workouts, diets, and the works. They'll often impart advice to the newbies and other gym members, and discuss everything with the instructor. You'll even spot them with the latest fitness gadgets and apps.
The sweaters are those who begin sweating the moment they touch a machine. They leave behind puddles of evidence of their presence wherever they work out. As far as hygiene is concerned, towels and deodorants are alien terms. If you're extra lucky, you'll even get to meet those who consider bathing and laundry optional too.
The competitors are synonymous with frenemies. They will compete over every little thing, whether it is running on the treadmill and burning x number of calories within a given time, or using heavy weights, maximum number of reps, weight-loss, etc. They are constantly trying to beat the other one's record.
Cell phone addicts successfully manage to distract everyone at the gym. They will talk nonstop on their cell phones. The moment their call is disconnected, there's a silent sigh of relief. But it doesn't stop there. If they're not talking on their cell phone, it will beep continuously. You can even spot them sitting idly on the machines, texting. Selfie addicts will flex in front of the mirror to click selfies and post them online.
You always have one of these guys at every gym, and sadly, you need just one to keep the rest waiting. Machine hoggers mostly have neither count nor reps, but they take as much time as they can on each machine. Then, there are the gym residents. These guys take machine hogging to a whole new level, by hogging the gym. They are present at the gym all the time, be it morning, evening, or night. It's as if they never leave.
