About Us
NRTHRN Strong is a boutique fitness concept born in Denmark — rooted in Nordic values, inspired by nature, and built on the foundation of cross-country skiing, one of the world’s healthiest sports. Grounded in functional training and fueled by community, NRTHRN brings the strength, resilience, and spirit of the North into every workout.
Our mission is simple
To redefine functional fitness by blending strength, cardio, and mobility into one holistic training experience - grounded in the resilience, balance, and spirit of the North.
Our Founder
Nicoline Roth
Born in Copenhagen with family roots in Norway, Nicoline embodies the Nordic lifestyle. Her love for the outdoors - especially the mountains of Vestlandet - shaped the design and philosophy behind NRTHRN Strong.
The studio reflects her passion for simplicity, warmth, and balance, inspired by hygge and the invigorating power of nature. More than aesthetics, Nicoline’s vision has always been about community - creating a space where movement feels joyful, connection comes naturally, and strength is shared.
A lifelong high-performer with a deep commitment to wellness, Nicoline discovered the NRTHRN Trainer and immediately recognized its potential. Versatile and transformative, it became the cornerstone of her own practice and inspired her to share it with others.
By blending Nordic principles of balance, connection, and resilience with the innovation of the NRTHRN Trainer, she brought NRTHRN Strong to life - not just as a studio, but as a sanctuary of strength, mindfulness, and community.
