The last person you want to see while you’re under construction is an ex.

They record their workouts complete with a full soundtrack. I barely have time for a 20-minute elliptical.

If it’s not melting off, you’re not working hard enough.

9. The Grunter

TRX suspended pushups like a boss. No, that's not me grunting in the background. #trxpushups #trx #squarereadyv #squareready #pushups #gymgrunters #gymmoaners #mondayfitness

They hog the mirrors, flex, make odd faces and take countless selfies.

11. The Hogger

Ugh. Just annoyed. Apartment xomplex gyms are annoying when 1 person is trying to circuit train while 2 other people are trying to train too. #ugh #machinehogger #caniusethat #sharingiscaring
