I have lived three years in the U.S. None of these club "chains" or "franchises" can compete with Megatlon´s Maure´s or Migueletes"
location (I can´t remember if it is on Maure or Migueletes), the treadmills, bikes, overall infrastructure is top notch, in comparison the New York Sports Club seems a city council free gym (and so crowded by the afternoons that you had to queue to run). Please note that I am pointing out to Center Maure/Migueletes and not the others. There´s a huge difference between this one in Migueletes and the rest.
I am posting the link below in case you want to have a look , there´s a "recorrido virtual" where you´ll be able to catch a glimpse of what the weight lift room seems like-I have never weight lifted in my life-I avoid weights, I´m more on the yoga/pilates track
