I've been going to FIT Brea since last year and it's been an amazing experience. Andrew and the…read morecoaches design workouts that are challenging, well programmed, and never repetitive. The environment is supportive, and the programming is perfect for people of all ages and fitness levels. The workouts push you to become a better version of yourself. If you're serious about reaching your fitness goals, I highly recommend checking out FIT Brea.

I'm so thankful I found FIT Brea! Over the past several years that I've lived in the area, I've…read morebeen a part of various gyms (both chain and boutique) nearby. Having now experienced FIT Brea, I'm definitely kicking myself for not trying this gym out sooner. I've only done their group fitness classes so far, which range from 8-12ish people in size, and I'm looking forward to trying out the personal training sessions when my schedule opens up! Here are a few ways that make FIT Brea a standout: COACHING: The coaches here are the whole package! 1. They all have stellar credentials, with many of them holding advance degrees and multiple certifications. In short, they know their stuff. 2. At the risk of sounding facetious, I just want to make the point that the FIT Brea coaches actually coach. It might sound like a no-brainer, but it hasn't always been my experience that coaches do much more beyond demo-ing the moves and saying "good job" or "keep going" every few minutes, especially in a group class setting. Here, the coaches constantly move throughout the room to offer individualized pointers on form, differentiated movements depending on individual strength and mobility, alternative movements for injuries, and encouragement and motivation to keep pushing so I can get better and better. 3. They are all super patient, encouraging, and welcoming! PROGRAMMING: The programming for the group classes are thoughtfully and methodically designed. From what I can tell so far, the workouts are structured in mesocycles with a progressive overload pattern. This is important because if we do the same thing over and over, our bodies will adapt and we will not make appreciable gains over time. With progressive overload, our bodies are constantly challenged so that we can keep increasing strength and improving hypertrophy. COMMUNITY: The FIT Brea community is so nice and helpful. I felt welcomed by the coaches and the other patrons from day one. Several people who recognized that I was new introduced themselves and helped me find and set up various equipment. Others even put my plates and dumbbells back during transitions. Just last week, the whole class broke out into spontaneous applause and cheer when I pushed out that last rep of bench press, haha! The mutually encouraging environment really underpins the whole vibe and experience here. It's a special thing. MANAGEMENT: One of the things that I didn't realize would make a difference in my overall gym experience is having direct access to management/owner. In my past gym experiences, the questions/concerns I had would typically have to go up a chain of command before I got a response. Since FIT Brea is owner-operated, the patrons can directly talk to Andrew, the owner, who is so nice and provides exceptional customer service. SPACE/EQUIPMEMENT: It's spacious, well-maintained, clean, and an overall pleasant environment to train in. CLASS OFFERINGS: I'm a busy mom who works full-time hours plus daily commute. I'm thankful that classes are offered as early as 5am and as late as 6:30pm so that I can get my training time in! If you are looking for a gym where you can optimize and maximize your fitness goals (whatever they are), look no further because FIT Brea is it! I'm a serial Yelp sleuther and almost never write reviews, but my experience thus far has so far exceeded my expectations that I felt compelled to share this gem of a place with others!

The coaches, Coach G, Coach Lauren, and Coach JB are incredibly knowledgeable and genuinely care about helping you improve. They've taught me so much and always push you to become stronger and more confident in your abilities. I recently started joining the gymnastics class and it's been one of my favorite parts. I love being able to work on skills, improve movements, and learn new techniques in a supportive environment. What really makes INTRVL special is the community. Everyone is so friendly and motivating you're surrounded by strong individuals who encourage each other every day. The gym is always clean, organized, and has an amazing energy. Coach JB also expanded the gym and added a 24-hour access side, which is a game changer. With a busy schedule, it's so nice to be able to train whenever it works for you without feeling rushed. If you're looking for a gym with great coaching, an awesome community, and a place that will truly help you grow, INTRVL is the place to be.

As soon as…read moreI arrived - although late for the class - staff Jackie & Brielle greeted me with such good energy that I felt more than welcome! After the class, I stayed a while to work out my upper body using a routine from the app, but the first exercise I wasn't sure how to attack & honestly figured I'd just head out because I'm big on form. I went to the front desk and spoke with Jackie, and she was more than willing to help me find the right machine, different modifications to work out what I needed, and the cherry on top was personal trainer Vincent, who assisted me with a quick session on all the questions I had for other parts of my workout. I went from ready to leave, to see you next time! & came back again with my mom today. She agreed they were just as helpful and pleasant. We will definitely be back!! Thanks Jackie, Brielle & Vince!

I've successfully completed 2 in two months and have already signed up for another.
