Trim Fitness Studio

Orange County’s premier Lagree Fitness + VersaClimber studios in Lake Forest, Costa Mesa and Brea!💚 Trim Fitness Studio welcomes all fitness levels.

Trim Fitness Studio offers a 45-minute high-intensity, total body Lagree Fitness workout on the patented MegaFormer M3. Lagree uses slow, controlled movements with constant tension to work your slow-twitch muscle fibers to failure...yes, failure. Our Lagree Fitness workout is unlike anything you've ever done, and we speak from first-hand experience when we tell you that the results are amazing. Not only do you burn an average of 600 calories per class, but your metabolism increases for the next 20-24 hours after class so your body can repair your muscles. With hundreds of moves and various resistance options, every class is different, keeping your mind and body guessing. In addition to Lagree, experience our 30-minute group training Climb Class that's calorie-blasting and uses your upper and lower body together. Unlike most cardio machines, the versa climber gives you no momentum, forcing your body to do all the work. Each certified instructor is skilled at managing different fitness needs in each of our classes. Lagree and Climb are the only workouts we have found that provide you with all the intensity you could ask for (and more) without the risk of damage to your joints or muscles. We can't wait to see you in the studio soon!

Hi everyone,

Some of you may have seen or heard about me around the Trim studios, so let me introduce myself properly. I'm Warren, and earlier this summer I became the new owner of Trim.

A bit about me: I've spent my career in finance and investment, much of it in London over the past twenty years, before recently moving back home to Southern California. For the next chapter, I wanted to be part of a business that people genuinely love, and that's exactly what I found at Trim. The instructors are here because they love their craft and the people they teach. The clients are here because they want to be. Everyone in the room is working on something, whether that's strength, health, headspace, or just an hour with good people. Getting to play a part in that, every day, is why I'm here.

Trim exists because of Melissa, and I'm lucky she continues to be involved. She's been exceptionally generous with her time and knowledge as I am settling into the business. The instructors, the classes, and the community that make Trim what it is aren't going anywhere. If anything, expect more of what you already love: continued investment in our instructors, our studios, and the small details that make the experience great.

That's me in the photo with my wife, our son, and our daughter. If you see me around Lake Forest, Costa Mesa, or Brea, please say hi. Tell me what you love about Trim, and how I can help make it even better.

See you in the studio,
Warren

Two completely different workouts. Both at Trim. Both absolutely necessary.

Lagree is the slow burn. Time under tension, not reps. Your muscles don't get a break, they just get stronger. Controlled, intentional, and deceptively brutal on the Megaformer.

Climb is the fire. Cardio, power, that moment where you're not sure you can finish and then you do anyway. High output, loud, exactly what your body needs after all that slow burn.

That's what makes Trim different. It's not one thing, it's the whole picture. The yin and the yang. The burn and the fire. We've been offering both for over 12 years, and nobody in OC does it like us.

Not sure which one's for you? Don't choose. Try both.

New to Trim? Grab our New Member Intro Offer for $20 off — 6 classes for just $109. Classes can be used for both Lagree & Climb and expire 45 days after your first visit.

Offer available through September 30th. Link in bio. 🔗

You just started strength training, and the scale went up. Before you spiral, read this. 🛑

When you start training, your muscles hold onto water as they repair and grow. And lean muscle is denser than fat. So your body is already changing shape. The scale just hasn't caught up yet.
Fat loss is coming. But your body has to build the engine before it starts burning more fuel. That's the order of operations. And right now? It's working exactly the way it's supposed to. The scale is not the whole story.

A few weeks in and second-guessing it? That's the most normal thing in the world. It's also exactly when most people quit.

Don't be most people. 💚
