http://www.mountaintraining.ch/ started up in Grienbachstrasse 15, Zug about two months ago, and it's a small but very nice, no-nonsense gym.
No wellness programs, no zumba classes, no slim belly stuff, no pilates, no power plate, no body toning classes or magic zirkels. Just a small and basic gym with all the equipment you need for a proper weight training session and nothing more.
For a warm up or a fat burning session after your workout they have is 2 running machines, a few bikes (spinning bikes as well as the normal ones) and four eliptic machines, and apart from that there are new weight machines all around (with ample weitghts), and a section with free weitghts and olympic bars for your squats, deadlifts, bench etc. Dumbells up to 25kg atm, but will be completed up to 60kg.
The prices are unbeatable as well. Less than half of what the Migros gym down the road is charging, and no join up fee. I went to see it last week, and joined up on the spot. Best place i have found in CH so far, so if you are looking for a place to get a proper gym workout and not having to pay for all the extras that you probably never use anyway, then this place might be worth a look.
