Justine Barnes
Yoga Guru & Spiritual Guide
Justine began her professional journey through many years of classical dance training. This early and disciplined relationship with movement prompted a deeper inquiry: what changes when we bring conscious awareness to the body? More than three decades ago, she discovered yoga asana and has remained dedicated to the practice ever since, drawn not only to the postures themselves but to the central role of breath. Through breathwork, she cultivated presence and, in doing so, reconnected with a sense of something greater – the universe within and around us.
​
Today, Justine teaches from a simple yet profound principle: breath is life. Her work with leaders and teams uses yoga-based practices to reconnect individuals with qualities that are already inherent: peace, clarity, compassion and inner steadiness. It counters the fragmentation and pace of modern corporate life. Her sessions integrate breath and mindful movement to deepen the connection between body, mind and spirit, and to activate the body’s natural capacity for regulation and renewal. The intention is not to create a new identity, but to support a return to a more authentic and grounded way of being.
​
The aim is to cultivate calm equilibrium, resilience and sustainable high performance, supported by practical tools that participants can apply in their day-to-day leadership. Trained by teachers and facilitators from around the world, Justine brings a gentle, intuitive and deeply empowering presence to all of her work.
