Ultimate Performance Personal Trainers Los Angeles, Brentwood - Los Angeles, California

If you are considering becoming a client at UP, don’t think twice. I had an incredible experience from day 1 and I cannot recommend Faith enough as a personal trainer! I have been working with Faith for approximately three months now, and in that time, I have seen incredible progress—not just physically but also in my overall confidence and approach to fitness.

Faith has an amazing attitude—she’s incredibly supportive, motivating, and genuinely invested in her clients’ success. She brings such positive energy to every session, making even the toughest workouts enjoyable. Her attention to detail is unmatched; she constantly ensures proper form, offers helpful corrections, and tailors workouts to maximize results.

This is NOT one of those gyms where the trainer is looking away, distracted on his/her phone, and letting your form slip without correcting you.

What I appreciate most is Faith’s ability to push me just the right amount—challenging but never overwhelming. She understands that fitness isn’t one-size-fits-all and takes the time to customize workouts based on individual goals. She also provides great insights on recovery and overall well-being, which made a huge difference in my progress.

If you’re looking for a knowledgeable professional, Faith is the one! I’m so grateful for my time training with her and highly recommend her to anyone looking to take their fitness and health to the next level.

This process was not easy, but if you’re ready to make a change, UP is the place to do it.

I've been with Ultimate Performance for about a year, and I really enjoyed my experience here. As a person who is afraid of going to gym, and doesn't really enjoy workout, this is a new experience for me, and I think I made a good decision in joining the membership here. I also want to shout out to my trainer, Candace.

The gym is nice, and trainer will also sanitize the equipment before you use it. Candace will give me regular checkin, and share knowledge with me about nutrition and how to have a healthy lifestyle even outside of the gym. I really appreciate how she pushed me to my limits , and I'm impressed by how much I've achieved with her and this program.

Highly recommended for people who are hesitant in going to gym/new to gym but want to have a lifestyle change.

Working with Ben McKnight has been a great experience. Ben helped me stay on schedule and stay motivated throughout the process.

Ben goes beyond simply designing workouts—though those were always challenging and effective. Instead of handing me a one-size-fits-all plan, he taught me how to make sustainable choices that fit my lifestyle after UP.

What truly sets UP apart is their unwavering support. Whether I was celebrating a milestone or struggling with motivation, they were always there with encouragement, advice, and a game plan to keep me moving forward.

If you’re looking for a trainer who is knowledgeable, empathetic, and truly invested in your success - Ben and Ultimate Performance is the way to go.

As someone who conducts intense research before committing to something important, I spent months looking up personal training gyms before I found Ultimate Performance—and I couldn’t be happier that I was paired with Reggie! Just three months into my program, I can honestly say he has been a game-changer on my bridal fitness journey.

Reggie’s workouts are always challenging, no matter how strong I feel, and he has helped me exceed my own expectations for building strength. His ability to tailor workouts to target my specific goals pushes me to my limits in a safe way that I wouldn’t have achieved on my own. Plus, his positive energy and incredible sense of humor makes every session enjoyable!

My primary goal has been to get into stellar shape before my wedding in June, with noticeable results in time for my dress fitting at the end of March. From our first session, Reggie was attentive, knowledgeable, and incredibly motivating. He crafted a workout plan that not only helps me fit into my dream dress but also keeps me toned as the big day approaches. The atmosphere at Ultimate Performance is professional and inspiring, making it a fantastic place to train.

Reggie’s guidance has been invaluable, especially with my hectic shooting schedule. His expertise in meal planning has been transformative, helping me stay on track, energized, and even travel while maintaining my lifestyle. In just three short months, I’ve lost 8% body fat, and with my wedding 5 months away, I’m so excited to see my final results!

If you’re searching for a personal trainer who truly cares and knows how to deliver results, I highly recommend working with Reggie!! His own fitness journey is inspiring, and he has an amazing personality that makes the experience even better.

Thank you, Reggie! You’re making my wedding prep an incredible journey! 💪🎉 Vogue Adria, here we come!

I have been going to the Brentwood location of UP for approximately 6 mos. and working with trainer Ben. The facility is comfortable and clean and all of the staff friendly and professional. Ben does a great job keeping me accountable and making sure we keep up with the goals we have set. I’ve lost 50lbs while increasing my strength and stamina over the time we’ve been working together. The one-on-one nature of the gym I believe keeps all of the clients comfortable and supports the generally light, supportive and friendly feel of U.P.

I’ve been training at Ultimate Performance Brentwood since January 2024, and the experience has been nothing short of transformative. Working with Octavian Shepherd has been a game-changer. For the first several months, I trained 1:1 with Octavian three times a week, and he consistently went above and beyond to help me succeed.

Octavian is more than just a trainer—he’s a coach, mentor, and partner in the process. He inspired me, challenged me, and taught me how to dig deep, stay focused, and achieve results I never thought possible. What truly sets him apart is the level of support he provides outside of the gym.

Octavian didn’t just guide me through workouts; he helped me build a deeper toolkit to achieve my goals. He advised me on selecting the right equipment for my home gym and even designed home-based workouts tailored to my setup. For my frequent travels, he programmed workouts that fit my schedule and available resources. His expertise extended to every facet of fitness, from mastering macros to navigating restaurant menus during vacations (yes, I even sent him links to restaurant menus early on!).

With Octavian, I wasn’t just following a plan—I was learning skills and strategies to sustain my progress long-term. He genuinely cared about my journey, and I found myself working harder not just for my own goals but to make him proud. That level of accountability and motivation pushed me further than I ever could on my own.

The truth is, achieving this kind of transformation rarely happens alone. If you’re ready to put in the work, go to UP and work with Octavian. It’s a life-changing experience, and I cannot recommend him or UP highly enough.

I've been training at Ultimate Performance with Jenna for the last 12 weeks and it has been the most amazing experience. I was initially resistant to joining because I worried about feeling restricted around food. However, it has been the exact opposite, I feel like I have a lot more freedom now because I have the tools to make healthy choices. I never feel like I have to miss out on a social event to achieve my fitness goals, because Jenna has helped me figure out how to make fitness work for my life. This program has been so wonderful for my overall health. Jenna has helped me build healthy habits not just with eating and movement but with prioritizing sleep and stress management as well.

The Ultimate Performance gym is a very friendly and motivating environment. You feel like people there remember you and you're motivated to work harder when surrounded by other people achieving their goals. The facility is easy to park at, which I consider to be super important when you're trying to go somewhere multiple times a week— it's very convenient! The facility also has great amenities both with the workout equipment and the locker room.

I am so happy with the fitness journey I've been able to go on after joining Ultimate Performance. Not only do I feel so much more confident in my body, but I also feel so much more physically fit. I can tell that I have more energy, an easier time with workouts, and am stronger after going through this program. I can really tell how beneficial this has been for my overall health. The workouts and training sessions are genuinely challenging, but Jenna is always super encouraging and I feel accomplished after completing them and look forward to my training.

Some places that promise results like this use fad dieting or an insane workout schedule that would be impossible to replicate after ending the program. Ultimate Performance is not like that at all. I genuinely feel that the program has helped me incorporate better habits into my life improved my lifestyle in a manageable way that I can continue doing to maintain my health for the rest of my life.

I've been training with Killian, and he has been an incredible partner in my health journey. Killian has my highest recommendation! He pushes me and really take every detail of my progress into consideration as he advises on movement precision and dietary shifts. He is also intuitive and shows patience when I am really working on a challenge. Terrific instruction, and I feel like my form and strength improves every session.

I am going through a number of challenges this year and coming to UP was intended to support me through those changes. I have learned more about my dietary needs for sure. And focusing on strength training is a shift that I’m enjoying! I strength trained previously but have made great progress week-to-week with Killian challenging me by my side.

I am still working toward my goal and am excited about getting there with UP. I feel like my body composition is shifting in this process. I’m excited to reach my goals as I continue into the new year.
