I absolutely LOVE Club SAR! I joined back in 2010 (I think...). At first, I just went there with my ex (who lived in So Cal and had been boxing) because I have always loved the sport of boxing and wanted to get into it myself (maybe even join the boxing team).  Sadly, I exceeded the age limit to join the boxing team, by a few years...  :-(
But, at least I could still learn and get fit.  :-)
We just walked up to the entrance and just took one quick look around and it seemed crowded and small so we were not impressed. So, we left.
I found out this used to be just a boxing gym before but eventually they added other classes and equipment for others to enjoy. 

Glad I went back later on my own and found out how affordable it was!
I checked and tried a few other Fitness centers and gyms nearby but, when I decided to actually try one of Club SAR's boxing classes, I was hooked! For a mere $3  (a day) drop-by fee, I was able to get one of the best workouts I ever had. I joined after I found out it only cost $75 for the whole YEAR which includes ALL the classes I can take (Boxing, boxing conditioning, Yoga, spin class, kickboxing, weight training, MMA... Yes! MMA too, which I personally love.  :-) ). Jonathan & Carlos are great and so is Tom. They're funny, friendly, and they actually remember you after only a few classes. 
The pricing has gone up this year but it is still by far, the BEST possible deal you can find anywhere in the Valley.

If you are serious about getting fit, staying in shape and getting a good old-fashioned workout without all the "posing" and pretentiousness of other gyms which are more like "meeting places" and "meat markets" for the young Scottsdale wannabes, this gym is definitely for you!

Personally, I recommend the boxing classes because they will kick your butt, they are fun, get you fit and, in shape. :-)
They just got new heavy bags so there are 2 heavy bags, 1 hooks bag, several "Bob bags", 2- double-ended bags and 3 speed bags in the main workout areas. Plus, a bunch more standing weighted-base heavy bags in the other "kickboxing/Yoga room. And, in case you didn't notice from the picture, a full-size boxing ring. 
Yes. I am totally endorsing this gym! 

P.S. This is a "no frills", serious gym. 
So, no whinnying and crying. Suck it up and do some push-ups!  ;-)
