    Having been going to INTRVL for a while now, I wanted to update my review. In the last year, the gym has only gotten better including new equipment and more focus on designing classes that touch on everything from cardio to strength training. They make sure there's something for everyone. The coaches really care, watching and correcting you when needed but especially showing encouragement to keep you motivated until the last rep. The gym also fosters a community environment. Everyone here is pretty much like family and we want to see each other push ourselves to the next level. If you ever need help with lifting, form, technique or gymnastics, you can always ask the coaches or the long time members. The gym itself is always clean because the owner/Coach JB puts pride in cleanliness and orderliness. He's here when they open at 5AM and when they close at 8PM. He takes time to keep all the equipment organized and cleaned after every use by our gym members. I've been to several other gyms and none have compared to what INTRVL offers. If you ever feel like you need a home gym, this is the place. Even if you are new to strength training, everyone here welcomes new members and gets excited to share their knowledge for those just starting. You will definitely get used to the support from the coaches and members. You won't regret giving this gym a try! The support you receive from everyone here will help you reach your goals quicker than other gyms because you will want to go to multiple classes a week and never skip a gym day.

    How much is monthly membership?

    I don't have an exact number but it varies depending on how many months you purchase. All I remember is that it is a lot cheaper compared to other boxes. Also their class package is super reasonable!

    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!
