1. The lust for cool workout clothes.

Nike, Adidas, Lulu Lemon and Under Armour have all my money. Also, Khloe K's fitness closet is goals.

2. Feeling secretly guilty about loving the high you get from taking pre-workout supplements.

It feels so good but the Internet says it's so bad.

3. Dreading the time when your tolerance for it has gone so high that you have to phase off for a while.

T minus three days until I can take pre-workout again.

4. Feeling possessive of your favorite machines.

How many sets are you going to do, man? Give me my machine back.

5. Giving anyone who takes your spot on the mats evil side-eye.

Go find your own spot.

6. Working out as a solution to everything.

Stressed? Go to the gym. Sleepy? Go to the gym. Bored? Go to the gym.

7. That feeling of utter despair when you realize the gym is closed AFTER you've already taken your pre-workout.

What do I do?! WHY CAN'T GYMS BE OPEN 24 HOURS?!

8. Gawking at the fitness gods that go to your gym.

How are you lifting that much? How are your muscles so defined? TEACH ME.

9. When you have to go for more than a few days without access to a gym...

Like a smoker deprived of nicotine, depriving you of exercise makes you sluggish, irritable and prone to unwise decisions.

10. Being grumpy for your whole workout because that one machine is broken.

Ugh, now I'll have to plan a whole new work out!

11. The euphoria-like zen that you get into when in the middle of your workout.

All your worries melt away and it's you, your heartbeat and your muscles.

12. Feeling so much more confident after workouts!

Yassss bi*tches, I'm on top of the world!

13. Waking up the day after a particularly grueling workout and not being able to move without wincing.

I'll just lie in bed until it doesn't hurt to move.

14. The struggle of going up and down stairs after leg day.

Also choosing to bend over 90 degrees to pick something up instead of squatting.

15. The struggle of laughing or sneezingafter abs day.

"Hahahahahaha OW!"

16. Looking in the mirror one day to realize that you've made progress.

Whoa... I have muscles.
