What happens when Scandinavian performance culture meets the intensity of New York City’s fitness scene?
In this episode of Marni On The Move, I’m joined by Nicoline Roth, founder of NRTHRN Strong — the Scandinavian workout sensation taking over the NYC fitness scene.
Born in Copenhagen and now making serious waves in New York, NRTHRN Strong is not your typical strength, cardio or HIIT class. At the center of the experience is a completely unique machine inspired by cross-country skiing — custom to the NRTHRN Strong workout — designed to deliver powerful, full-body conditioning in a way most athletes have never experienced.
The workout blends conditioning, strength training, and cardio into a high-performance, interval-based format that challenges endurance, power, and mental grit — all within a strong, community-driven environment.
Nicoline shares the vision behind NRTHRN Strong, how she translated Scandinavian training principles into an innovative boutique fitness concept, and what it takes to grow a brand in one of the most competitive fitness markets in the world.
We dive into:
- The structure and flow of a NRTHRN Strong class
- The proprietary cross-country ski–inspired machine that sets it apart
- How conditioning, strength, and cardio are intentionally programmed
- Building community through performance
- Expanding from Copenhagen to NYC — and East Hampton
- Lessons learned as a founder
- Creating and leading a strong team of instructors
- Nicoline’s daily wellness rituals and breathwork practice
- Finding balance in New York City
- The power of setting intention — in business and in life
This conversation is about strength in every sense — physical, entrepreneurial, and personal.
If you’re curious about the future of performance-driven training and the next evolution of boutique fitness, this episode is for you
