1. The grunter -- maybe they're aware of it, or maybe they're jamming out so hard they don't even realize they're doing it. Either way, it's awkward

2. The personal space burster -- even though there are 11 other open treadmills, they insist on working out on the one right next to you

3. The mirror dater -- this person really, really, really enjoys checking there muscles out. Watch out buddy, you don't wanna pass out from flexing so hard

4. The excessive layer wearer -- it could be 80 degrees in the gym and this person will still be dressed like the blizzard of 2016 is occurring right there on the workout machine

5. The shaker -- this person is so into mixing up their protein drinks they may as well be working out with a shake weight

6. The familiar face -- the person you always see at the gym and make awkward eye contact with but never really actually talk to

7. The dresser to impresser -- yeah, we know you have no intentions of sweating in that outfit you're wearing *cough cough* hot yoga pants
