Gymnesia 

When you have not been to the gym for an extended period of time due to laziness or any other poor excuse.

Donnie: Where you been homey, I haven't seen you in ages?
Greg : All this partying is really taking its toll. I have severe gymnesia!

gymbelina 

Similar to the girl in the fairytale Thumbelina, she is the short, beautiful, and muscular girl you always see at the gym. What she lacks in height she clearly makes up for in her strength, and would frighten even the tallest of men with the veins on her arms.

"Hey, did you see that little girl benching 100lbs? She couldn't weigh much more than that! Clearly she's one of those gymbelinas."

I haven't seen Billy for a while. Where's he got to?
That guy's got a bad case of Gymnesia!
