In the ever-evolving world of boutique fitness, Solidcore has quickly become one of New York City’s most talked-about workout experiences. Known for its high-intensity, low-impact strength training, Solidcore offers a powerful 50-minute class that blends elements of Pilates with resistance training for a results-driven, full-body workout. Designed to push muscles to their limits while remaining accessible to people of all fitness levels, Solidcore is redefining what it means to train with intention.
What Is Solidcore?
Solidcore’s unique methodology is rooted in slow, controlled movements performed under continuous tension using a custom reformer machine known as the Sweatlana. Unlike traditional Pilates, Solidcore’s approach focuses on breaking down muscles to the point of failure. This process—often referred to as “second-stage muscle failure”—stimulates the repair and rebuilding of muscle fibers, resulting in increased strength, endurance, and definition over time.
Inside a Solidcore Class
Stepping into a Solidcore studio is like entering an immersive fitness experience. The dim lighting, energizing playlists, and personalized coaching all contribute to an atmosphere that feels focused and empowering. Each movement is performed slowly to eliminate momentum and increase time under tension, which is key to engaging type 1, or slow-twitch, muscle fibers. These muscle fibers are responsible for stability and endurance, making Solidcore an excellent choice for building long-lasting, functional strength.
Class Formats for All Levels
Solidcore offers a variety of class formats, each designed to meet clients wherever they are in their fitness journey:
-
Starter50 – A beginner-friendly class introducing the reformer and the fundamentals of the workout.

-
Advanced65 – A longer, more intense session for seasoned clients aiming to maximize endurance and strength.
The Science Behind the Results
Solidcore’s training philosophy is backed by science. By keeping muscles under constant tension, the workout maximizes metabolic output and muscle engagement with every second. This technique specifically targets smaller, slow-twitch muscle fibers—often overlooked in traditional strength routines—that are critical for stability and sustained toning. The result is not just increased muscle endurance, but also a visible tightening and sculpting of the body.
In fact, many participants report feeling noticeably firmer and more toned immediately after class. The trembling or “shaking” sensation experienced during class is a sign that muscles are being deeply and effectively engaged, particularly in commonly desired areas like the core, glutes, and arms.
Low-Impact, High-Intensity: A Safer Way to Strength Train
One of Solidcore’s most appealing attributes is its low-impact nature. By minimizing strain on the joints, the workout significantly reduces the risk of injury, making it ideal for individuals recovering from physical setbacks or those seeking a sustainable long-term fitness regimen. Despite being low-impact, the intensity remains high—challenging your body while promoting safe, functional movement.
Because the focus is on strengthening slow-twitch fibers, clients often find themselves better equipped to handle everyday physical tasks—from walking and lifting groceries to playing with their kids—thanks to improved core and stabilizing strength.
A Core-Centric Approach to Full-Body Fitness
As its name suggests, Solidcore places a strong emphasis on the core. Every movement—whether it’s a lunge, plank, or squat—requires deep abdominal engagement to maintain control and alignment. The Signature50 class begins with a core warm-up and then transitions into a dynamic rotation of lower body, upper body, and oblique-focused exercises. While the sequencing may vary, each class is designed to deliver a comprehensive full-body challenge.
For those seeking targeted results, classes like Focus50 and Power30 are tailored to isolate specific muscle groups such as the core, obliques, and upper or lower body. This level of customization ensures that participants can hone in on their goals with precision.
