Orangetheory Fitness

Workout aspect was good but the reason I am giving two stars is because they don’t respond to customer’s emails, phone calls, and messages.
Totally unprofessional and unacceptable in any business. Good way to turn business away and garner a bad reputation.

Love this place! I am an avid excerciser, but sometimes need motivation to push myself and this is the place to do it.
It is an hour long workout using treadmills, rowing machines, and weight training. The head trainer Mike is awesome! He is motivating and even though a group class he will come by and assist you with your form and whatever you need. Heart monitors are used to show your progress. The time goes by quick and I feel invigorated when leaving. The workouts change daily so you will not plateau or get bored. This workout may get me to run a full 5K yet (I am sooooo not a runner). LOL!
I can’t wait for my next workout!

Orange Theory Fitness does a workout involving treadmills, rowing machines, and strength training with barbells, TRX bands, and body weight exercises. The workout involves HIIT — High Intensity Interval Training. 20 years ago when you did your cardio, the trainers wanted you to get to your target heart rate and stay there. HIIT is about bringing your heart rate up high for a minute or two burst and then take it down for a minute and then bring it back up again. Also in decades past when you’d go to the gym, you’d do your cardio, then do your weights and then you were done. Here they mix that up quite a bit. You might do a 3 or 4 minute interval on the treadmills, then 5 minutes of 3 different weight exercises, then 4 minutes on the rowers, then 3 more minutes of strength training. When you’re doing your cardio work, you might do 1 minute at a base training heart rate, then 1 minute at a push pace with a higher heart rate, and then 30 seconds to recover, and 30 seconds all out running or power walking as hard as you can on the treadmill. Basically you’re always moving and there is no resting and you don’t do anything long enough to get tired of it or too exhausted. The workout is 1 hour and it flys by. You can always look up at the monitors and adjust your intensity to fit the heart rate the trainer wants you to be at at any particular point in time. Each class has about 20 or so people that split up into 2 groups working different stations together. The music is loud and it’s almost like a dance club with the funky orange light they have in the studio. You have an instructor that leads your through the workout. I’ve done 2 classes with Aundre and he is awesome. High Energy, Positive, with great workouts with lots of short intervals to mix it up. I’ve been to 3 different orange theory fitness studios and I like Centennial the best. The workouts are much better and go by quicker. It’s worth driving further to get to this one in my opinion. Oh as far as results, I’m burning 800 calories in the hour and supposedly even more after the workout. I can tell already after 2 weeks of doing this my heart is much stronger and my heart rate doesn’t stay as high as long. Also I’m getting nicely toned and stronger. To me the benefits seem to be coming quite fast. This is a highly effective workout. You can sign up for a free class at
I’m finding the classes fun and it’s actually quite addictive and when you’re done you feel like you really accomplished something.

Orangetheory is the BEST hour long workout I have experienced! The staff and the trainers are not only very warm and welcoming but professional as well, making sure to connect with each member to help them reach their goals! I love how each time I train it is a new workout, allowing my body to not plateau! I recommend people from all fitness levels to give OTF a try because the workout is designed to challenge you at and meet YOU at your level of experience! LOVE LOVE LOVE OTF!!! It’s worth the investment!

I like the workout overall. For me, the heart rate thing should be optional. The monitors are really hard to look at during a very hard treadmill interval, so you really cannot see your zone or you may land on your ass. So, I know I’m working hard, but it’s too bad they can’t place those readouts in an easier to see way. Also, I’m not crazy about it being public, it’s kind of lame to me. I don’t care on the one hand, but I guess I may not want other people seeing that I’m slacking!
I’ve been to Centennial and Lowry. I love the two instructors that I had in Lowry and the energy of the participants is always upbeat and great.
Centennial classes are good, I really like Aundre. He is very helpful and very nice. I had a Monday morning class a few times with Max. He plays music that I don’t care for (i know that that is very individual), but the music is very loud and it’s hard to hear his instructions sometimes. Also, there is a very annoying participant who whistles and it is irritating and ridiculous. I’m sure she is a happy person and is trying to be a motivating force in the class, but I don’t care for it. I think it’s childish and disruptive. I like when people are into a class and the energy is good, but this was over the top for me.

A friend of mine has been going to the OTF in the Highlands for a while, and he raves about it. They’re working on opening one close to where I live, but in the mean time I was able to snag a free week pass to the OTF down in Centennial. It’s *sort of* on my way to work, so for a couple workouts a week it’s not too bad.
The facility is great. The workouts are pretty intense, and all designed to keep you in the «orange zone.» You see, everyone gets a heart rate monitor, and there are big screens at two ends of the gym so you can see your heart rate. With zones from blue at the bottom for resting, to red at the top for over 100% of max heart rate. The rates and which zone they fall into are different for everyone, and based on age and resting rate. The goal is to spend as much time as possible in the orange zone, as I said, and because of that, you are instructed to vary your intensity to accomplish that goal. It isn’t about keeping up with the rest of the class, it’s about challenging yourself.
So far it’s been a lot of fun. Great circuits, great exercises, and really fantastic positive leadership and coaching from the trailers. They’re energetic, encouraging, and helpful. As a guy who’s default mode is to be pretty embarrassed about doing group classes, this has been an incredibly comfortable environment for me.
At $ 99/​mo for a membership that includes 8 classes per month, the prices are a little steep — but you’ll get out of it what you put in. Use these fantastic workouts as building blocks for your other workouts during the week. I’m excited to join an OTF Fitness Challenge and see how much weight I can lose!
Oh, and not only is the staff super awesome re: classes and questions and memberships, they’ll also totally jumpstart your car for you when you’ve been an idiot and left your lights on during class and your batteries have died. So, bonus star for that!

So far, so amazing!
I have been a member for almost a week, and I have been going to their Orange-​60 classes and their TRXta classes at both the Centennial and the Highlands Ranch location. I think that I will need to update this review in 8 weeks with my results, but so far I am obsessed with the energy level of the classes and the people that work there. It’s great to be in an environment where people love what they do and want to pass that on to everyone they interact with. It’s contagious! I haven’t felt this good since I was running regularly.
The way that this workout is superior to running is the half cardio/​half strength training sessions. Their philosophy is that if you keep your heart rate in the orange zone (I believe that’s 80−85% of your max) for a certain percentage of your workout, you reach maximum efficiency in fat burning. I haven’t been doing it long enough to see results yet, but based on how sore I am and how much more energy I feel throughout the day, I would venture a guess that it’s working. My plan is to do this a minimum of four times a week for the next eight weeks, and I won’t be surprised if I meet my fitness goals by then. I will update at that time!
