Going to the gym is always an interesting experience. Even if the gym is part of your daily routine, each time you go there is always something different. However, whether you're a hardcore gym rat, or an occasional visitor, there are certain commonalities we all experience from time to time. From funny people-watching, to gym envy, to the mid-workout lull, here are some thoughts we all experience while paying a visit to the gym.

1. Where did all these people come from? It's never this busy.

2. I swear, half of these people must have just joined.

3. That girl’s outfit is so cute, I wonder where she got it.

4. Why don’t I have any gym clothes? Mental note: invest in stylish workout apparel.

5. Oh no. Oh no. Did I forget my headphones?

6. Thank god. False alarm.

7. Ugh that guy is using my favorite machine. Doesn't he know I always use that machine at this time?

8. I guess I’ll try something new. Hmm, wonder how this one works?

9. Act cool, you can totally figure out what this machine does, it's not rocket science.

10. OK, OK, abort mission, no clue how this works.

11. Wait she’s headed to the machine, let’s see what she does.

12. Ohhhhh, that’s how that works, OK. Good to know for next time.

13. Yes, my machine is finally free.

14. OK, time to get serious, let’s do this.

15. How long has it been? Can I be done yet?

16. Just forty-five more minutes you can do this.

17. I am really regretting that extra cookie last night.

18. Ten minutes, push through.

19. Woohoo, all done!

20. Oh thank god, the endorphins kicked in.

Endorphins are the best part of exercising -- just hope that happy feeling carries over 'til tomorrow when you have to pay another visit to the gym.
