WHY OUR APPROACH WORKS

Booty Builder Zone

The only studio in the area with a certified Booty Builder Training Zone. Our glute-focused machines will help you build strength, shape, and confidence through purposeful, results-driven workouts.

Small Class Sizes

Each class is capped at six members and led by a dedicated coach, allowing for precise instruction and real-time feedback. Training stays focused, distraction-free, and highly personalized.

Intentional Training

Our training is built for strength—not random challenges. No outdoor runs or burpee marathons. Each movement is chosen to build muscle, improve strength, and drive long-term progress.

Hybrid Training Areas

We have created an unrivaled training floor spanning over 5,000 square feet. Group classes flow effortlessly through specialized zones built for precision, tempo, and seamless movement.

Specialized Classes

We offer 3 class types: glute-focused, full-body, and upper-body/core. Each week, you’ll experience different workouts within each class type, helping you train multiple times per week with variety and balance.

Member-Only Access

Entry is reserved exclusively for members through secure mobile key access, maintaining a controlled training environment designed for focus and privacy.

At First Strength, we’re proud to be an official Booty Builder Training Center — home to an extensive selection of industry-leading Booty Builder machines, the global gold standard in glute-focused strength equipment used in thousands of gyms across 180+ countries.

Our dedicated glute training zone is designed to deliver unmatched muscle activation, optimized biomechanics, and targeted results that aren’t just about aesthetics but functional strength, performance, and long-term health.
