“This gym has the best coaches I have ever had in the 8 years I've been doing CrossFit. In the past, I've become used to the "coaches" at many locations being babysitters who just tell you the workout and watch you do it. But here, each coach has such great information, they give you cues before and during the workout to make sure you have proper form and technique. Just that alone makes this place a 5 star CrossFit affiliate. On top of that, the gym is nice and spacious with plenty of floor space and equipment for everyone. The programming is great, the community is very supportive, plenty of parking, very clean, lots of class times to choose from, and there's even a shower! Come check it out and I'm sure you'll love it as much as I do :)”

“Been training at Fitness Underground with Daniel since September 2023. I can already notice huge transformation in my strength, posture and energy levels. I walked in months after having a baby and Daniel got me strong enough to run after my little guy. Friends and family notice the weight loss and transformation. Not to mention, he gives food tips and tricks to get the most out of your diet. Highly recommended Daniel for personal training and the weights at Fitness Underground.”

“CrossFit Fortem has been a game-changer for me! It’s not just about getting fit; it’s about pushing your own mental limit. The atmosphere is always positive, and the coaches are super supportive. But what I love most is the sense of community. Whether we’re sweating through a tough workout or just hanging out after class, there’s always a feeling of camaraderie and support. I’m so grateful for this place and all the awesome people I’ve met here!”

“Been coming to CrossFit Upland since September ‘20. It was my second go with CrossFit, having left my first gym to find better programming, and I couldn’t be happier with CrossFit Upland. The WODs are always varied and challenging, and the coaching is consistently helpful to improve form, efficiency, and power while maintaining safety. The owner, Chad, seeks out opportunities to learn and grow as a coach and this trickles down to his other coaches as well. Lastly, the people are great, starting with the owner, creating a welcoming and fun atmosphere, as well as some friendly competition if you’re looking for it. If you’re looking for a box, I couldn’t recommend this one high enough!”

“This is my home gym. When I say this is my home gym, it's because I live less than 10 min away and it is by far the best gym in the area. The Staff is great, along with the overall cleanliness of the gym. Oh, and if you want to do outdoor activities, they got that too. The works made the adjustment of moving from LA to the IE easy. I'm grateful.”
“United fitness is the best gym I’ve ever been to. The trainers are really nice and actually care for your well-being. I started off coming here in April of 2022. I got introduced by the 21 day free trial, and that’s how I started off. It is completely free, you don’t even have to put your card in until the end of the 21 days if you want to proceed coming to this amazing gym.”
“Perfectly designed workouts that are designed to your ability, in a group setting. Teamwork and family, not egos and braun. Team workout and food challenges are great motivation as well. This is the best workout you will find..”
“So, I was in horrible shape... even though I was going to 24hr fitness. The truth is that I wasn't actually doing the correct exercises for my body... I stumbled upon this gym and decided to pay for private training ... and now I can I can say with certainty that it is the best decision I've ever made... I'm healthier, firmer and generally happy to push myself to become stronger. Also working out with a trainer one on one helps me to stay focused ... now you can pay and train as a group but I find it distracting. I recommend this place... it's the best money you'll ever spend on your health!”
“I usually go to the orange location but orange is bouldering only. I came to upland for Auto belay training. There are 2 Auto belay reels with 3 routes of varying difficulties accessible from each reel. The class was brief but covered the safety and using the Auto belay device and harnesses. There are quite a few top rope climbs and lead climbs in the hangar. There are a good number of bouldering areas. Unfortunately there were very few V0, V1, and V2 level bouldering problems.”
“Attentive and friendly staff. This location cares about their company and you can tell by the cleanliness of locker rooms, the stocked up supplies and they have the Best hot showers out of all local gyms.”

“Incredible place to train, no matter what level you’re at. All of the coaches are extremely knowledgeable and experienced coaches. What I love most is that their styles and methods complement one another. It’s also a true brotherhood! I couldn’t imagine training anywhere else. ??”
