About our service

Movement is structure. Strength is strategy.
At 143, we reimagine strength training through the lens of Pilates. Our sessions focus on slow, intentional movements that build deep core control, flexibility, and sustainable power. With small class formats and certified coaches, every session is tailored to help you move with precision.

‍
We train power, control, rhythm, and endurance using three formats inside the Arena:

M1 — Motionformer Pilates

Slow, controlled strength training for balance, power, and core stability.

R1 — Reformer Pilates

Precision-based conditioning that builds strength, length, and alignment.

MP1 — Mat Pilates

Foundations, breathwork, control, and deep core activation.

Every class is coach-led, technique-focused, and designed to help you train like an athlete.

Our Approach

We train for longevity, not just intensity.

In a world obsessed with hustle workouts and fast results, we do things differently. Our approach is grounded in technique, tempo, and form, with movement patterns designed to support your everyday life—not wear your body down.

We emphasize quality over quantity, building strength that’s functional, graceful, and sustainable.
