I signed up for a 12:15 class at their LoDo location for what’s called Endurance Pull. They offer four other classes POWER push, Power pull, FlghT36, and pulse36.  All the classes offered are a HIIT circuit, last for 36 minutes, and the class routine is the same for 2 weeks. This allows your body to get familiar with the movements and then changes things up with a different circuit to conquer in two weeks. Basing their concept on claims that your body gets used to repetition, FIT36 switches up the movements so that you can continuously benefit from their 36-minute workouts. 

The LoDo location has two studios. When I arrived, another class was finishing in studio 1.  They were doing a combination of TRX and weights. My class, in studio 2 was a combination of spin and weights. Each variety offers a circuit with a unique emphasis and a different apparatus. You alternate between cardio bursts (bike) and then strength training (weights). Each studio has a monitor that shows you how long each interval of the circuit is. You push yourself hard for about a minute, then go at a slower pace for a minute, but add more resistance. Then, you all-out sprint with no resistance for a minute. These sprints are all done on the bike. During the weight segment, you run through two exercise series, 4 different movements in each, for 2 sets. The class is divided in half, and one group starts with cardio, one group starts with weights. As time counts down, you swap back and forth from weights to cardio. 

Our instructor was helpful in demonstrating the weight circuit and preparing the class for what was next.  FIT36 promotes the benefits of barefoot training and encourages you to try their classes without shoes. For Endurance Pull, because I personally don’t like the feel of pedals on a spin bike in bare feet, I chose to keep my shoes on. But there were clients spinning without tennis. 

As for the vibe, I loved the LoDo location. It’s urban, with exposed brick and steel. Being downtown on Market street made parking pretty tough though. If you live downtown, and FIT36 is within walking distance, that would be ideal. 

Circuit classes seem to be gaining popularity and with FIT36 having similarities to Orange Theory and Shred415, clients have options on what type of exercises they like best and how much time they want to devote. For instance, if you don’t care for Orange Theory’s treadmill, maybe you would prefer FIT36. If you don’t have 45 mins to an hour to spare for Orange Theory or Shred415 then again, FIT36 might be your jam. If you like tracking your metrics in class and competing with the group FIT36 might not check all the boxes for you. Although you can use heart rate monitors in FIT36, they don’t push it, and you aren’t racing against your own time or other students in a class.
