I gave you many routes. I've been in fitness for almost three years, and I've been to several gyms, none of which have been listed above, but I personally think the gyms are almost the same, with basically the same equipment, but different brands. No matter how good the conditions are, it is useless to practice without losing money. I suggest you go to the nearest place to have a look. If you feel uncomfortable, I hope it will help you.
