gymsterling

Someone who frequents a gym very frequently among other sports and mixes them up, such as martial arts, calisthenics or others, also looking both cool and hot.

Yoga pants girl: "hey who's that smoking hot stud with the sixpack there smacking the shit out of that punching bag?"
Another yoga pants chic: "Don't know but his bech press is way higher than those steroid pumped airbags can do! I'd totally eat that gymsterling!"
