1. You're a master of treadmill multitasking.

You can tie your hair up, create a playlist, and set the incline in one fell swoop. All whilst running full pelt.

2. You know the names of all the fitness instructors.

And they know yours. And you're Facebook friends.

3. Your workout shoes cost a small fortune.

Ain't nobody got time for shoddy support during Abs, Bums and Tums.

4. You know the class schedule by heart.

"Am I free Wednesday? That's TRX night. No, sorry, I'm not."

5. You know how to work a sweaty hairstyle.

The showers are NEVER free when you need them. So you make do.

6. The last thing you treated yourself to was a foam roller.

You got tired of only being able to use one at the gym. And it has *literally* changed your life.

7. People are always suggesting "new" workouts you should try.

But you've tried them all. Been there, done that, got the sweaty T-shirt.

8. You prefer gym clothes to normal clothes.

A Sweaty Betty shopping spree would be the absolute DREAM.

9. You never leave the house without your gym bag.

And you can pack it in 30 seconds flat. And not forget a thing.

10. You always have a post-workout snack to hand.

You should buy stock in Bounce Balls.

11. Your iPhone's recent places says 'Virgin Active' more than 'Home.'

Your 'cost per workout' is basically zero.

12. You've embarrassed yourself so many times during a workout you don't even care anymore.

From slipping on your own sweat to exposing yourself to everyone in spin class, there's no gym faux pas you haven't made.
