Coach John was very helpful and frequently went around giving clients feedback, so you almost feel like you have a personal trainer. The gym really is so nice, new, and clean. They also let you borrow gloves. You can try one class for free (with your friend) or a whole week for $5. I paid $5 and went twice so far, after all it is a small business. Love the energy in here!

The classes are just so amazing and each time I leave so happy. I love the strength training component, the coaches are the best and teach how to do the movements. I hate working out in the gym bc l'm always worried about my form, but here the coaches will correct you etc and teach you the right way. John B, Peter and Val make the classes challenging yet doable which I love. Also the other members are so nice and welcoming. I was so scared going by myself but literally everyone who works there and goes there are like the nicest people ever.

I've been to multiple F45 locations and normally love the format, energy, and professionalism that…read morethe brand is known for. Unfortunately, F45 Sunnyvale feels like a major outlier -- and not in a good way. I'm genuinely surprised this studio is still operating under the F45 name, because the experience here doesn't reflect the same standards I've come to expect. Trainers at this location don't demonstrate exercises live, they just mirror the video playlist from an iPad onto the TV screen and leave it at that. One coach in particular gave off the impression of being completely new to the F45 environment -- they didn't look or carry themselves like a trainer at all, and there was no engagement or technique correction throughout the session. It made the class feel unstructured and even unsafe at times. The equipment and studio upkeep also leave a lot to be desired. The space feels gritty and worn down, lacking the clean, energized environment that most F45s provide. I couldn't help but compare it to F45 Branham Park or F45 Mountain View, which are both far superior in terms of coaching, energy, and maintenance -- and they're priced similarly. If you're thinking of trying F45, do yourself a favor and explore one of the other nearby studios. Sunnyvale's location simply doesn't deliver on the brand promise, and I walked away feeling like I wasted both my time and money.

I've been a member at the Santa Clara location for over 6 months, and unfortunately my experience…read morehas been pretty disappointing. One of the biggest issues has been the constant turnover of trainers. Several have disappeared without any communication to members. Along with that, the training schedule has been very inconsistent, which makes it hard to stay on track. For me, building trust and a solid relationship with a trainer is essential to getting the best results. Having to repeatedly adjust to new trainers, while they also have to relearn my limitations and goals is frustrating and disruptive to progress. What's even more concerning is the lack of response from management when these issues are brought up. From conversations I've had, other members are feeling the same way. It gives the impression that there isn't much care for employees, and that ultimately impacts the member experience. I really wanted to like this gym, but the inconsistency and lack of communication have me reconsidering renewing my contract.
