Lepers of the health club.
People who make you wish you had bought a Bowflex instead.
Dude, why does that gymbecile need three sets of dumbells to flex in the mirror? What a fucking gymbecile.

What is she wearing? Has she confused the gym with the strip club. Gymbecile!

Is he power-cleaning in flip-flops? Fucking gymbecile.

This is a public locker room, not your private bathroom. Put some pants on you gymbecile.

Today, I created a new word:

"gymbecile"

A gymbecile is someone who, at the gym, uses weight equipment for extended periods of time, because they are playing with, or talking on, their phone. Another usage: a person who says they have one more set on the machine you are about to sit in, even though they are on a totally differentiate machine. Thirdly, any gym goer who attempts to touch another gym goer trying to "help" with form. And lastly, the plural form, gymbeciles are any group of males who think you can't hear their lewd comments.
The chick is a total gymbecile, playing her candy crush while sitting on the leg press for 20 minutes.
That gymbecile is gonna get a mouth full of metal if he doesn't back off. I know how to do tricep extensions.
