Owner. Trainer. Yogi.

Petra Jahn founded ZenRock Fitness in 2008 to create a safe, inclusive space where people of all backgrounds and abilities could feel empowered through movement, education, and personalized care. A lifelong athlete and former collegiate basketball player, Petra turned to yoga in 2000 to help manage the demands of school, sports, and work. That experience reshaped her approach to fitness—from chasing performance to pursuing lifelong vitality and connectedness.

With over two decades of experience, Petra blends strength training with yoga and mindfulness to help both men and women build strength, reduce pain, and feel connected to their bodies. Her certifications include a 500-hour yoga teacher training and mindfulness certification from 8 Limbs Yoga, as well as Dr. Stacy Sims’ specialized training in perimenopause and menopause. She’s passionate about educating herself & clients, supporting healthy aging, and preventing injury with smart, compassionate coaching.

For more than a decade, Petra—alongside new co-owner Nova Guthrie—has led transformational yoga retreats both nationally and internationally. Together, they’ve created unforgettable experiences that foster deep connection, personal growth, and lasting memories. Retreat destinations have included Bali, Tuscany, Portugal, Costa Rica, Greece, Croatia, and U.S. gems like Zion National Park.

In 2022, Petra and Nova expanded ZenRock by opening a second location in Bellevue, WA, continuing their shared commitment to building a vibrant, supportive community where strength, mindfulness, and holistic wellness come together.
