The Origins of La Forme

Hi, I'm Erin! I first fell in love with mega-style reformer workouts 15 years ago while living in Los Angeles. It wasn't until returning to this workout years later – this time as a parent and leading a global operations team for a Fortune 500 company – that I truly understood why I needed this in my life.

The reformer became my sanctuary. For 45 minutes, nothing exists except the burn and shake of each movement. No emails. No notifications. Just you and the machine. Within weeks, I found mental clarity and increased confidence. Within months, I saw the physical transformation everyone raves about (Google “Pilates body”!).

La Forme merges my passion for fitness with 15+ years of building exceptional teams and client experiences. We are creating more than a studio – we’re building a community where strength meets support. Where the transformations we create extend beyond the studio walls. Welcome to fitness, reformed.

Our Values

Core to how we show up for one another in and beyond the studio.

  • Community is the heartbeat of everything we do. Where you workout and how it makes you feel is more than a transactional event in your day. When you walk through our doors, you're in community with like-minded individuals who lift each other up and celebrate victories together. We believe magic happens when people come together with shared goals, whether it's in the high-five after crushing a challenging set or the encouraging nod during those final reps. These connections transform your fitness journey from a solo mission into a shared adventure, creating ripples of positive change that extend far beyond our studio walls. The stronger we are for ourselves, the stronger we can be for all of our communities.

  • Determination is the unyielding commitment to pursue goals and overcome obstacles, embodying persistence, resilience, and a strong drive to achieve one's objectives. It manifests as consistently working towards goals, refusing to give up when faced with challenges, and maintaining a positive attitude even in difficult circumstances. At La Forme, we demonstrate determination by showing persistence in the face of difficulty, adapting to find solutions, and maintaining a strong sense of purpose and direction in our fitness journey.

  • We believe that the journey to feeling your best should be joyful, embracing playfulness to create a welcoming community and make fitness more approachable for everyone. Our playful spirit permeates every aspect of our service, from warm greetings to engaging instruction and communal celebration of milestones, all within a vibrant, thoughtfully designed studio that serves as a third space for connection. By fostering an environment of curiosity and enjoyment, we're not just helping clients achieve fitness goals, but also encouraging them to embrace a sense of play and form lasting, positive habits.

  • Showing up on time isn't just about watching the clock—it's about showing up for yourself, right now, when it matters most. Every time you make it to your session on time, you're choosing to put yourself first (how often do you do that?). We match your commitment by making every minute count: classes start and end right on schedule, equipment's ready to go, and transitions are seamless.

    Sure, being punctual helps us run a tight ship and keep everyone safe, but more importantly? It's about making the most of this time you've carved out for yourself. Because let's be real—there's never going to be a 'perfect' time to focus on your fitness. The time is now, and we're here for it.
