Why train at Ultimate Performance Brentwood?

Brentwood attracts clients who care deeply about how they look, how they perform, and the standard of service they receive. Many of our clients work in law, medicine, real estate, or the film and entertainment industry, and they expect precision, discretion, and results.

The U.P. Method is built for this level of clientele. Our Brentwood trainers are incentivised and targeted on the one metric that matters – the quality of results they deliver for clients. When you train here, every detail is planned and managed for you, from training and nutrition to accountability and progress tracking. There is no guesswork and no wasted effort.

This is not a typical Los Angeles gym. There are no classes, no open gym access, and no distractions. It is a private, appointment-only space designed for one-to-one personal training, where every session is focused on improving body composition, performance, and health metrics.

There truly aren't enough adjectives in the English language to describe how great an experience it has been to be a part of U.P. This place has definitely transformed my physical and mental health to the point where I look forward to working out. Having a trainer who pushes me and doesn't let me get away with any BS, but is also super caring and supportive has been a massive motivator for my success. I would never have been able to get to this point on my own

After many failed attempts of getting in shape on my own, I realized the missing piece: Accountability. Ultimate Performance takes you every step of the way, from strength training, to meal planning, to check-ins, to an app with updates on your progress and connection to your trainer. I don't have to think about counting reps, or trying to figure out what my body is responding to, or even figuring out a workout plan - all of it is done for you.

Nothing is more valuable than your health. UP Fitness easily is one of the hardest things I have ever done in my life and yet the best decisions I have ever made. I am the strongest I have ever been in my life, the most energetic I have ever felt, the happiest that I can remember. The scary part is UP reminds you that this is just the beginning, there are no upper limits.

My trainer has taken me from a lazy, undisciplined overweight 47-year-old who’s never really worked out in his life…. to a lean strong, never-been-in-better-shape, healthier version of me ever! Also because of the style of workout with BOTH diet AND exercise, for the first time in my life I actually ENJOY working out. Im now one of those people in a good way!

Efficient outsized results: The answer to the question of why would you invest this amount of money?! There is no true magic. You have to do the hard work. The "magic" is in their system, expertise, controls, and data. It's analogous to going to the Mayo Clinic for a major medical issue except this is for body transformation and general health. Results you won't achieve on your own.

At U.P. Brentwood, you are not just buying training sessions. You are committing to a results-driven system led by elite coaches who are selected and rewarded based on outcomes.

We track more than 50 data points each week to guide training, nutrition, and recovery, all within a private, appointment-only gym environment. The focus is on measurable body composition change, not generic workouts or short-term fixes.

How much does personal training at Ultimate Performance Brentwood cost?

Everything at U.P. Brentwood is tailored to you, including the price. Your investment depends on how often you train, your availability, and the results you want to achieve.

During your consultation, we will explain the options clearly and provide a bespoke quote based on your goals. This includes coaching, nutrition, body composition analysis, progress tracking, and ongoing accountability.

 Do you offer a consultation before joining?

At U.P., aesthetics and health are treated as complementary outcomes of a structured, well-managed process.
