Matt: Man, Kevin must workout all the time...all he ever wears are sweatsuits.
Mallori: Kevin never works out. He says he hates it. Trust me, he's a gymposter.

gympostor 

One who walks around in workout or gym-like clothing to give the effect that they have worked out or gone to the gym today or are planning to work out or go to the gym today when in reality they have not or are not going to. One usually does this to make oneself feel better about their physique or to seem like they are physically fit when in reality they have done nothing today.

Look at that girl in the nike shorts, under armour shirt and asics sneakers with a pony tail. She is totally a gympostor. I didn't see her at the track or the gym at all today.

Gymposter 

(A) People who are obviously not serious about getting in shape but attend a fitness club (usually at the request of a significant other) and hog the machine, bench, or area that a serious and courteous member would like to use, remaining there for an exceptionally long time, and are intentionally putting forth little physical effort due to being naturally lazy. (These annoying pricks usually decrease in numbers as it gets farther away from January 1st.)

"All the treadmills are occupied. That one fat gymposter has been there for 25 minutes and hasn't even walked a quarter mile. Get the hell off and go back to the dairy farm, you prick."
