A person, usually male, with hair-plugs and pectoral implants that places a workout towel on a machine and proceeds to complete one slow, very light set on a different machine with exaggerated form. Then, the same person will walk around the gym for about 15-20 minutes before their next set, hoping to see someone they know that also would rather socialize than workout. They wear very baggy clothing to hide their lack of proportion, especially in the leg area.
There goes the workout impostor, he's only done 2 sets the entire time I've been here, and I'm finished my workout!
That workout impostor would rather socialize and fix his towel than get results.
