The best gym, my favorite gym! Lots of equipments, professional trainers, very modern, cool…read moreinterior design! Love the huge space and it is the place where you can totally forget about anything else, stressless, and ENJOY workout. There is AC, so you don't have to be struggled by the hot weather. The window view is nice, and you see many pretty people working out there with you is A+++. Love the steam room, sauna, lockers, group lessons, energy bar, and especially the spin class (with steam if you want more challenging to your exercise). They gave you two towels. I think this chain store is sponsored by Armani. You only see Armani advertising in the entire area which is fine with me. Feel even more high-end. :)) The cost is a bit pricy. One day pass is $50, but people, it gives you AC if you know what I mean. I was at CMG, I paid $35. If you get out of the gym, cannot come back anymore unless you pay another $35. It was a small place filled with lots of people. Not enough equipments, less selective of facilities. No AC, no view. I thought I was like a blue shrimp swimming in a hot pot getting cooked. There is a gym at Latin quarter where asks for a same amount of fee, much older than CMG, same quality, but it has a big swimming pool on the 2nd floor. I was at a health club yesterday on Champs Elysees near Marriott hotel and it at the same building where Starbucks is located. It is at the basement, asking for $40/day. Big place, so so equipments, no street view, I felt kind of gloomy and suffocated already and I haven't even started working out. So if you really want your workout in Paris feels like a treat, come to L'usine!!!
