    Electrum performance is by far the best gym I've trained at! The coaches on the floor are extremely knowledgeable, easy to talk to, and are there if you have any questions at all regarding form, a potential injury you may need to work around, or just targeting a specific muscle group that can be difficult to target. The workout programs that are given are curated just for you for any and all of your fitness goals/needs! Whether you're a bjj athlete looking to improve your stamina, improve your grip, gain strength, or just someone who wants that strategic and serious workout plan, this is the perfect gym! The atmosphere is extremely positive and the community is delightful to be around. If you train bjj (or if you don't) and are looking for a gym that will focus on your improvement, this is the gym for you

    I love Electrum Performance! I've been working out with Alex as my trainer since 2018 when he was at another gym and couldn't be happier that he decided to open up his own gym. He's one of the most friendly, intelligent and helpful humans I know. Electrum Performance is more than a gym. It's a community. The trainers and members here are all fun to be around. Many of the athletes here practice Ju Jitsu which I do not. However, this private gym is perfect for regular work outs as well as Ju Jitsu. It's a nice change of scenery from the big box gyms where things can get too crowded. I love the programs that Alex writes up for me. It makes it easy to track my progress. Highly recommend Electrum Performance!

    Electrum Performance is not your average gym. The owner and staff are actively involved in helping you design a workout routine designed to meet your strength and conditioning goals especially that for Jiu Jitsu related goals. The personal training offered here goes above and beyond the expectations a member might have when first walking through the door. Owner Alex Sterner is actively involved in public demonstration for proper technique and workouts that target specific areas of training on social media platforms. With top of the line equipment, a turf strip, and jiu jitsu mats, Electrum Performance has everything you need for top quality performance. They specialize in perfecting workout technique and you may discover workouts you have never thought of.

    My favorite gym experience. Alex and team knows their stuff, especially if you're a jiujitsu practitioner. I was looking for a trainer that knew had to manage a severe neck injury and the team has been helpful in managing it while helping me grow stronger. If you're looking to optimize your strength and performance, look no further.

    When I first met Alex it was so refreshing to work with a trainer who wasn't a "bro", if you know what I mean!

I've had the pleasure of being instructed by Coach Danny Perez, Danny Llagas, Aaron, Aemetrius, Christina, Alex Medina and Nate...and I will say that my favorite instructor is always whoever is teaching that day and time because they are all phenomenal. Sasha and Kevin have been so great working with my kiddos in the kids boxing classes, I'm astonished at how quickly my kids are picking up the sport, all credit to the coaches. Ron and Ashley and AD are always warm and welcoming, they set the tone for the culture here, it truly is second to none! I also want to boast about the staff's willingness to change the music from adult to more family friendly for when my kids are in session, this means a lot to me and I know that it might resonate with other families hesitant to try this place out. You are in great hands here! Thanks Odyssey!

Nobody has egos and the staff is personable. I take the Muay Thai classes with Coach Dom and Caine. I like how very detailed they are in explaining and how they correct everyone's technique. I've also learned a lot from my PT sessions with Coach Aaron and Coach Dom. Highly recommend checking out Coach Danny P.'s power boxing classes. I have fun coming here with my workouts because everyone is friendly. The jujitsu mat is the center of the gym so I enjoy watching the students roll. Everyone motivates each other here! This training center is SOOOO clean. They clean the floors, mats, equipment daily. They even have a "living room" area where your kids can play while you're working out, 10/10 Totally recommend! Glad I joined!

Fast forward a few months later and I am still here because it has become way more than just a gym to me. What makes this place different is how personal everything feels. Sean genuinely takes the time to understand your goals, your habits, and why you are trying to make a change. It never felt like I was just another membership or being thrown into some generic workout plan. I am someone who likes understanding the data and reasoning behind things, so the detailed scans, movement analysis, and check ins were a huge plus for me. Sean always took the time to walk me through the results in a way that actually made sense and helped me understand what needed improvement, not just physically, but with recovery, consistency, and overall lifestyle habits too. The culture at The Fit Lab is also something special. Everyone is welcoming, supportive, and there is zero ego. You get honest feedback, accountability, and a team that genuinely wants to see you succeed. I originally came in wanting to improve my fitness, but I ended up learning a lot more about how to train properly, recover better, and build habits that actually feel sustainable long term. If you are looking for more than just workouts and want a place that truly cares about helping people improve their lives, I highly recommend Sean and The Fit Lab.

If you're someone who's motivated by data, feedback, and understanding the why behind what you're doing, this gym is an incredible fit. Sean, the owner, genuinely takes the time to listen, ask the right questions, and dig deeper into your goals and motivations--not just what you want to achieve, but why it matters to you. Some of my favorite highlights include: * A supportive, welcoming culture with both the team and other members * Curated workout plans tailored to your individual goals * In-depth data analysis and consultations to ensure you're on track * Flexible scheduling * Honest, real feedback--no fluff, just what you need to hear What I appreciated most was how Sean consistently walked me through my data, clearly explaining what was working and what needed adjustment, always backed by evidence. Beyond changing my physique, The Fit Lab helped me build better lifestyle habits and truly understand how to train correctly--and what that consistency can lead to long term. If you're looking for more than just workouts and want education, accountability, and real results, I can't recommend The Fit Lab enough.

Originally why I stopped coming was due to how crowded and unorganized it was which was such a deterrent! After the recent remodel with up to 18-20 Squat Racks, additional benches/dumbbells, and more Leg Machines, I started coming here over my favored UTC, but now that UTC downgraded from 11 Racks to 6 and removed the outdoor area in favor of potential Pickleball Courts I will not be going back unless they can bring back what they had before or even better as it's not a great place to go anymore for a Powerbuilding workout. For a Push Pull Leg workout between 3-5 days a week Balboa really hits better now and my only gripes are if they had more of the nice water bottle refill stations and cleaned the bathroom more since people come in from the pool and leave the ground wet, but the plumbing and cleanliness here is still better than at UTC which seemed to not make any changes on that front. If the dumbbells were organized as well that would be great but I can see how hard it is to manage. Overall this is my new home for now and definitely would recommend as it's not as seemingly as crowded before with more equipment availability. 3 stars but I would put 4 if the place itself was more organized and bathroom was always clean and dry!

The problem is this location has a serious overcrowding problem, so it can be difficult to use the equipment you want without waiting a lot. If you can find a time to go when it's not crowded then it's five stars. My two cents: 24 hour fitness nearly went out of business due to the pandemic and closed several locations in San Diego. Well, everyone has been back to the gym with a vengeance for a few years now and they need to open new locations.

She always demonstrates the exercises and teaches modifications, which is so helpful, especially if you're newer to this style of workout or need an adjustment. Her classes are upbeat, motivating, and always a great workout. I'm pretty much guaranteed to be sore the next day, which tells me I'm getting stronger! I also love the studio itself. It's beautiful, has such a clean aesthetic, and the atmosphere is really welcoming. I especially love that the workouts feel more like strength training than traditional Pilates--it's exactly what I was looking for. As someone who still modifies some exercises, I've never felt judged or out of place. Mia creates such a supportive environment, and I've always felt comfortable working at my own pace while still being challenged. I'll be trying other instructors soon, but Mia's Sunday morning class will definitely be my weekly go-to. Highly recommend if you're looking for a fun, challenging workout in a gorgeous studio!

After the class was over, Jimmy met with me to go over packages while he allowed my children some extra time during the open play. Jimmy was extremely nice and my children had a lot of fun! However, I felt the price didn't quite match the quality. The facilities appeared pretty run down. It seems this was an old gym they took over. If not, perhaps it hasn't been kept up as well as it could have. There is NO ac and it doesn't exactly smell fresh, though I understand as it's hot and people are running around. I was considering the open play package as I felt it was a reasonable price, but for only one hour a day, it wasn't worth it. If you do decide to more forward, I recommend scheduling the classes right before an open play so your child has more time. But for the price, personally I would expect nicer/cleaner facilities.
