Also bear in mind that 1 January, 1 May, 18 and 19 September and 25 December are mandatory retail holidays, when most shops close.

Visiting Santiago and this gym has been an absolute gem of a place. Super modern. Not too crowded. Great staff. All the equipment to do anything you could ever want. Truly the best ive found in santiago. They have a 2 week pass and a month pass that I was using while visiting.

A wonderful gym. The staff was very friendly explaining everything about the gym. There are plenty of equipment and lockers. What I liked the most was that they put the equipments in the order of the work out so I don’t have to go around looking for it. The stretching area was nice and it was nice that they had a vending machine in case you need something. They also had an eating area. The lighting system was good and they have a nice mirror room where you can see your muscle work out progress from almost every angle. The gym also has nice places to take pictures and record content if you’re a content creator. Most of the people here seem like they work out really hard. It could be because I went at around 4pm but it wasn’t too crowded which made it pleasant to use. I also love how they have wipes available every where so that you can clean the equipment before and after you use it.
