Just Like The building of Rome, with the right Tools, guidance, and discipline you can sculpt yourself into a beautiful work of art that you will be proud of and others will admire. I started working w/ Calvin for strongman in hopes he can take me to the next level. I was hesistant at first, but after talking and getting to know him more i took a chance and its a chance i do not regret. Within just a month of getting coached by him not only has my strength improved, but so has my endurance and believe me, like most people I hate cardio but the method he implements cardio along w/ strength training has pushed my Strongman limits passed what i thought were possible. And we are just getting started. If youre debating on signing up to recalibrated or debating on getting coaching from Calvin, i can wholeheartedly testify that he will get you to were you want to get and further.

5-Star Review for Recalibrated Gym in Upland

We’ve been coming to Recalibrated Gym in Upland for years, and it continues to exceed our expectations. What sets this gym apart is the incredible family atmosphere and the genuine care that the owner, Calvin, puts into every athlete’s development. Calvin is deeply invested in building not just strength, but also skill and resilience through proven, effective methods—no shortcuts here.

My son had a nagging injury that had been bothering him and within a month of focused work at Recalibrated, he only felt better but also strengthened the injured area. The attention to detail and individualized approach made all the difference.

The gym is filled with quality people who are supportive and encouraging, creating an environment where everyone thrives. Members include middle school, high school kids and adults. Calvin and Trinh are top-notch and truly good people who are passionate about what they do. If you’re looking for a place that will push you to be your best while making you feel like part of a family, Recalibrated Perfomance is the place to be!

I've started training at Recalibrated in 2021. At first I was just there for open gym. Eventually I joined team training around February 2022. The community is super encouraging especially at the end of the training block when everyone is testing their 1 rep max. It gets rowdy and it's a lot of fun. Coach Calvin is super friendly along with his wife Trinh. They recently moved to their new location in downtown Upland which is super spacious. The team training focuses on the big 3 powerlifting movement: squat, bench, and deadlift. Do not be intimidated. I have seen first hand people start with the barbell and grown into strong individuals. It's a matter of consistency. There is a morning session and an afternoon session (Monday, Wednesday, Friday) Morning sessions are run by Coach Marco. He's super accommodating and fun to train with. It doesn't matter if you're just starting, jumping back on the saddle, or looking for a group to train with, come check this place out. I said I'd give team training a try for a few month in Feb 2022. Two plus years later and it's wild home much more stronger and fit I've become! Consistency Consistency!

One thing to note about the gym. This isn't a commercial gym. You get a space to train where you don't have to deal with inconsiderate people taking up machines, checking themselves out in the mirror, and leaving equipment all over the place.

This is the best gym in the Inland Empire. No matter what your goals are, this is the place that will help you accomplish them. Calvin and Trinh, the owners, are some of the nicest people. They are always there to help, encourage, and coach you along the way. However, they aren’t the only ones; if they’re busy, there's always someone who will jump in and help in any way you need. The owners will make you want to start, but the community they’ve built is what makes you want to stay. There are few places where I can go and know there will be people supporting me and cheering me on, but I know I’ll get that as soon as I walk through the door. If you want to see what you’re truly capable of, surrounded by encouraging people, Recalibrated Performance is the place to be.

I’m a full time working mom of two younger kids and over 40 years old. I started with a 6 week challenge a year ago and I’ve been hooked since. It’s intimidating to lift for the first time in your life but the coaches (thank you Calvin and Marco) and the people who are part of this community are the most encouraging, supportive and non intimidating community to have rooting for you. Owner Coach Calvin is so knowledgeable, kind, and super down to earth and always willing to help and is so generous with his expertise. I love that there are set times for workout sessions because it’s the only way I can have accountability. I’ve gotten stronger, feel competent navigating barbells, and I especially appreciate the coaches’ expertise around issues of recovery when that’s needed. So thankful to this community of all around good people which makes regular workouts so fun!

I’ve been working out here as part of the women’s group training (strongHER) and although I’ve worked with personal trainers before the level of knowledge Calvin and Tim have is great. They are very good with all training levels and incorporate a lot of different aspects of training other than just lifting (ex. Mobility).

I've been training here for about a year now, and I must say that it is the most positive training environment that I've ever trained in. I was originally in the StrongHER program once a week, and since then, I've moved to the team training, training 4 days a week with a mix of upper body, back, and lower body. The coaches are knowledgeable and providing guidance during the trainings. Everyone that trains at this gym are extremely encouraging and always ready to HYPE up breaking your next PR.

This gym is amazing! I really enjoy Tim and Calvin guiding me through some recovery exercises for running. Additionally, the strong her program is amazing in that it builds community with the other women in it. They look out for each other and encourage each other. Thank you for providing a safe space for all types of athletes.

Wasted my time. Spoke with this Asian man working there about coming in for a training session and called before hand to confirm and when I got there it was a mess. He was very nonchalant like he had no idea what he was doing and when I said that he got upset and was chewing his gum harder, as if that’s helpful. Ego, they don’t know what they’re doing makes the place look bad I was hyped cause the reviews but straight up DISAPPOINTING. Wasted my time.

In just under 3 months, I have learned so much from both Tim and Calvin as Coaches! The community at Recalibrated is so supportive. While you get to challenge your individual strength, you are never alone. I feel so fortunate to have found this community. Building my muscle strength, I have been able to transfer this to my cardio and increase speed. Calvin and Tim are great at showing you proper form and offering even pre & post work out care. Regardless of what your fitness and athletic goals are, you will come out knowing more and being stronger. Thank you Recalibrated Performance!!

Awesome little gem hidden next to Downtown Upland. Everyone here has a common goal and I've had a welcoming experience. There's a really cool atmosphere as everyone is willing to offer advice and seem to genuinely care. Definitely suited for all levels whether beginner or advanced. There is a lot of cool equipment you won't see at typical commercial gyms and I definitely recommend getting a tour. Also, members are asked to practice sanitary guidelines like wiping down equipment which is a great comfort during the pandemic. Shout out to Tim and Calvin for all the help.

I have been training here for the last several months and my experiences thus far have been excellent. The owners of the gym are friendly and welcoming, as are the other members. The equipment here is well kept and maintained. Recalibated Performance has a private gym atmosphere and offers many amenities to its members both in training and recovery. My favorite amenities that the gym offers are 24 hour access and the ability to sync music from your phone via Bluetooth directly to the gym speakers.

Love this gym! I'm a runner and I realized that I needed to incorporate strength training into my training. Calvin has been so welcoming and always there to help us out. I do his strong (her) training program and I can see a difference of how much stronger I have become. He explains every exercise down and what muscles it gets and the reason for it. It has made lifting not feel as intimidating. He teaches us so by the end we can be able to set it up and do it on our own. Love the community environment!!

This is hands down the best gym I’ve been to. They have all the equipment you need for any body type and any goal. They’ve been extremely accompanying during Covid, while also staying safe in the process. They’re open 24/7 so you can get a lift in whenever you want. By far the best thing about this place is that the people there are like a family, and they genuinely want what’s best for you. Calvin and Tim are the owners, and they’re always there chatting it up with people and trying to push everyone to their full potential. Calvin is also a personal trainer, and he’s always giving me advice on techniques, maximizing performance, and making sure I recover. Definitely good for anyone who’s trying to get/stay fit!

The gym offers machines that I had never seen in other gyms, I didn’t know how to use them at first so Tim helped me out & OMGGG truly loved them! They also offer student memberships & their prices for a private gym are amazing! If you’re really into weightlifting you’ll also love their “chalk station” & how they have different bars & accessories just for squats , deadlifts & bench 😍 .

My first day at Recalibrated Performance, I sat down with Head Coach Calvin, I felt at ease, confident in his programming, and couldn’t wait to start.
I have lifted and exercised in multiple venues. I even spent 10 years in the gym industry as well, but I knew walking into this place I wanted to find the closest thing to a forever gym I could.
However, this place is so much more. I call this a Power Gym, not just for powerlifting and not just a recovery center. This place emPowers individuals to push their limits and keeps them safe while doing it.
For anyone that wants to get stronger, needs recovery, or is even is a competitive athlete, this is the place to be.

Great gym found just right next to downtown upland, Ca

This gym has the potential for anyone looking to get strong, build muscle and get ripped. From squat racks to weights, to bench press and deadlifts, there are no cable machines here. Pure weights, and that’s what I like about it. You got to WORKOUT for real

Great selection of Olympic bars, special machines to help you increase your squat number

The owners are always available and they’re very helpful.

24/7 access? Can’t beat that

Also the gym is YouTube friendly and you can film your workouts , they also offer tripods so you can use them and keep track of your own progress like that

Started working out at this gym on January 1, 2020. The trainer, and owner, Calvin Law is a wonderful trainer. He really helped me reach my goals of getting stronger. He has the top of the line machines and his workouts are very personalized. I asked him to help me improve my diet and he also I corporates that as part of the program. The location is great, very quiet with plenty of parking space. Great vibes and great people. Highly recommend this gym. Wished I knew about it sooner.

Basic numbers: January 1 --> March 1
Bench: 165lbs --> 215lbs
Squat: 275lbs --> 325lbs
Deadlift: 315lbs --> 345lbs

And my strength continues to grow.

You guys are awesome. Thanks for being so committed to your craft and willing to teach the proper techniques to a new member in the weightlifting community. My first month at Recalibrated Performance we concentrated on strength and conditioning for this years past Los Angeles marathon. I am so happy I made the decision to do it. We were able to set a strong base and a personal goal to accomplish for the Marathon. Coach Calvin used to run competitively in his past. So I got super lucky having him guide me through my journey. He also works a lot of the local running groups as well. So safe to say we are in good hands.
