Mars Athletic Club is owned by Mars Entertainment Group, which owns and manages also NumNum, Nu Pera and Mars Cinema. Operating 3 clubs in Istanbul and one other in Ankara, Mars Group manages a total of 4 sports clubs around the country. They keep expanding quite fast, so it may be a little time before they open a 5th one. The Kanyon branch in Levent (which is in the vicinity of the commercial and financial hub of the city) is the white-collar branch that attracts many business people that arrive for fitness training after a day of arduous office work.
