I originally came in just wanting to fix my form and learn how to lift properly, and that's what…read moreI've been getting. Kacy is big on progression and basically operates under the assumption that you can always go up in weight, which has pushed my strength up (especially hip thrusts and RDLs). It's small group training, which keeps the energy up because everyone's working at the same time. He'll keep you accountable and make sure you finish your sets and there's a decent chance you'll leave with a random nickname you didn't ask for but it does keep things entertaining. In my first month I've already seen measurable changes in strength and body composition, so it's been interesting to see the progress show up pretty quickly. Curious to see what the next couple months look like.

My girlfriend had been working with a conditioning coach for some time but saw minimal results. We…read moredecided to shift focus and look for a strength-based training approach, which is when we found Kacy. We met with Kacy in person, where he clearly explained how his program works, reviewed pricing, and discussed the nutrition expectations that accompany the training. He was very straightforward, professional, and understanding--especially recognizing that it can be difficult to transition away from a previous coach. Training began shortly after. Sessions can be busier during certain days and times, typically running 60-90 minutes, with multiple clients training simultaneously. Despite this, you receive excellent value for the cost. The pricing includes gym access, which is a great benefit. Kacy maintains a professional environment while keeping sessions engaging, motivating, and appropriately challenging. It's important to note that this is primarily a group training format. While Kacy provides guidance and instruction, he is not overseeing every single repetition. For those who are completely new to lifting, discussing one-on-one sessions would be beneficial. Overall, we highly recommend Kacy. Thank you, Kacy, for your patience, professionalism, and continued support

Long overdue review for Peach Body Studio! I signed up for…read moreone of their programs last year and truly enjoyed my experience. One of the things I loved most was the atmosphere--it's an all-women's studio, which made it feel comfortable, supportive, and never overcrowded or overwhelming. All of the trainers are amazing--encouraging, knowledgeable, and genuinely invested in helping you succeed. I especially appreciated how welcoming everyone was, no matter your fitness level. Unfortunately, I wasn't able to renew my membership due to what I initially thought was a minor walking injury I experienced in June. After an X-ray, my doctor said everything looked fine, so I continued working out at Peach Body with modified exercises. Toward the end of my membership, I even transitioned into personal training sessions with Cheli, which helped me tremendously. I had every intention of rejoining after my six-month membership, but I had a trip to Spain planned. When I returned, my knee still wasn't improving. I ended up seeing a new doctor and, after an MRI in January, found out I had a torn meniscus. Fast forward to February, I underwent meniscus arthroscopy surgery. I'm currently on the road to recovery (still in a full leg brace), but I'm hopeful and looking forward to rejoining Peach Body Studio in a few months once I'm fully healed. Overall, I highly recommend this studio to anyone looking for a supportive, empowering environment with fantastic trainers!

I've been going to PeachBody Studios for about a year now, and I can honestly say it's been such a…read morepositive experience for me. I actually found PeachBody after having a really bad experience at a previous gym, so I was a bit hesitant at first. But from the moment I started here, everything felt different. The environment is welcoming, supportive, and truly empowering. What I appreciate most is how comfortable I feel during my workouts. It's not intimidating, and there's a strong sense of community. The coaches are encouraging, knowledgeable, and genuinely care about our progress. They always striving to educate us--whether it's proper form, technique, or understanding how to get the best results and our diet which makes a huge difference. The workouts are effective and focused, especially for glute and full-body sculpting. I've noticed improvements in my strength and confidence, which has been really motivating. I'm really grateful I found this place. It's a space where I feel supported by others and encouraged to keep showing up for myself. Highly recommend to anyone looking for a positive, women-focused fitness community! I would like to add too HUMOR! Expect To Laugh A Lot!

They provide you with a meal plan, a guide with instructions to help you succeed, and training classes are available morning and evening during the challenge six days a week. The trainers do a great job of staying on top of you by making sure you keep pushing and also making sure you are doing exercises correctly. I highly recommend you give this challenge a try, but only if you are willing to commit. Although all the tools are provided, there is a lot of will power that is required by each individual to succeed. Following the instructions on the guide are a must. Looking forward to challenge number 2 starting on January 9th, 2023. Highly suggest joining the 5am class, there is a lot of consistent members and this helps you stay motivated. Thank you to all the trainers and staff at the camp.

But they can always modify for any skill level. The trainers have a bunch of energy and really motivate you to want to try your best.

I've been working with Mia for almost 6 months now and have dropped about 5% in body fat and gained…read more7% in muscle mass. I would have never considered myself "overweight" but knew I needed to lose a few pounds. I've tried the traditional membership gyms but always found that I would lose interest or motivation. When I started inquiring about personal trainers, Mia was very prompt at answering. During our consultation I did a body fat scan and was shocked to find out that I was nearly 25%. We talked and I learned that it was less about the weight and more about body composition and fat/muscle percentages. Due to my work schedule we were able to meet twice a week for an hour a session. Mia adds good variety to our workouts and I definitively know that I push myself more during our sessions that I normally would have if I were doing the workouts by myself. She also places an emphasis on nutrition and offers advice on what to eat and what to stay away from. The last couple of years my diet has gotten progressively worse, and she's been a great help in getting me back on track. I've noticed that I've started making much healthier choices in the foods I eat. still have a ways to go but would highly recommend Mia for helping you get you to your goals!

Best Bootcamp Around!…read more I can't say enough great things about this fitness bootcamp! From the moment I started, I felt welcomed and motivated. The workouts are challenging but doable for all fitness levels, and every session pushes me to be better than I was the day before. Mark and Albert are absolutely incredible trainers. They're knowledgeable, encouraging, and truly care about everyone's progress. They know how to push you without making you feel overwhelmed, and they always make sure your form and safety come first. Their energy is contagious, and they make every workout fun while still delivering serious results. The atmosphere is positive, supportive, and motivating -- it really feels like a community, not just a gym. Since joining, I've felt stronger, more confident, and more consistent with my fitness than ever before. If you're thinking about joining, don't hesitate. This bootcamp is a game changer!

Brian and Kim are not only incredibly professional, but they genuinely care about your experience and your results. From the moment you walk in, they make you feel comfortable, welcomed, and completely at ease throughout the entire process. What really sets them apart is how thorough they are. They don't just hand you your results-they sit down with you and explain everything in detail so you actually understand what's going on with your body. They'll point out where you're doing well, where you can improve, and give you real, practical advice to help you get there. It never feels rushed, and you can tell they truly want to help you improve your health. On top of that, they offer more than just DEXA scans-they have programs and guidance if you're serious about leveling up your fitness and overall health. If you've ever thought about getting a DEXA scan, this is the place to go. Health is wealth, and Brian and Kim are the real deal. 10/10 recommend-honestly, if I could give 11 stars, I would. You will not be disappointed.

I cannot say enough good things about WELLTH Performance and the powerhouse duo of Brian and Kim…read more Since August 2024, I've lost 120 pounds -- and I still have another hundred to go. I knew I didn't want to just "wing it" anymore. I wanted real data. Real numbers. Real strategy. So I booked a DEXA scan, RMR test, and VO2 max assessment -- and it turned out to be one of the best decisions I've made on my health journey. From the moment I walked in, Kim made me feel completely comfortable. She openly shared her own health journey, which immediately put me at ease. There was zero judgment -- just understanding, encouragement, and genuine care. And then there's Brian -- my numbers guy. A skill I never mastered. He lives in the data in the best possible way. Everything we do is based on measurable results. If something isn't working (though so far everything is going great), we adjust. No guessing. No ego. Just smart coaching. I'm currently on a GLP-1 and my goal is not just to lose weight -- but to maintain and build muscle during the process. Brian actually increased my caloric intake after reviewing my RMR. That felt completely counterintuitive to me... but trusting the data paid off. I ended up increasing my RMR by around 700 calories per week. That alone blew my mind. When I aggravated my knee working in my garage (not workout-related), we simply adjusted the programming for a few sessions. As Brian says, "You're of no use hurt." Thoughtful. Strategic. Sustainable. He built me a workout program I genuinely look forward to. That has never happened before. What I didn't expect was how much I would actually enjoy working with them as people. They are as much friends as they are coaches. My wife was so inspired by my results she went in and got her own DEXA. Ending 2025 with a DEXA and stepping into 2026 with Brian and Kim in my corner was the smartest move I could've made. If you're on the fence -- just do it. WELLTH is the real deal.

Just lately I've felt like the owner isn't focusing on bettering the equipment or cleaning it at that. There's a section that's open where a Pilates reformer used to sit (idk if that's what it's called) but every time I'm working out I see that empty section and the paint is all ugly the section is dirty in general. I think if they spruce up the place a bit more and keep up with cleaning this gym would be TOP 5 in Chino.
