Our Mission
If you found your way to Otrain Wellness— you are ready for profound change. Not just in your body, but in your overall relationship to yourself. Welcome, we have been waiting for you.
After 10 years as a personal trainer, yoga teacher and energy healer working with over 500 clients in NYC, San Diego, Tulum, MX and globally— Olesya discovered a key reason that prevented clients from making progress and long-term, sustainable results: a disconnect between mind, body and spirit.
Leveraging a range of expertise and modalities, Otrain developed a holistic approach to fitness and wellness — architected to be completely unique to you. Empowering you to actively transform your body, nurture your mind and align with spirit.
About OLesya
Olesya Zreratseva comes from a long lineage of healers and educators. Her path of transforming deep pain into purpose has become a guiding light for others on their own journeys of healing. Through her personal awakening from sexual trauma, Olesya discovered her sacred calling — to help others remember their power, their softness, and their connection to the Divine.
A certified Hatha Yoga Teacher, Reiki Practitioner, Thai Massage Therapist, Personal Trainer, Breathwork Coach, and Sound Healer, Olesya blends the wisdom of the body, energy, and spirit into experiences that touch the soul.
As a Holistic Coach and Embodied Healer, she creates safe, transformative spaces for release, renewal, and remembrance. Her grounded presence and connection to her guides invite others to meet their shadows with compassion and let the light pour through.
Rooted in generations of healing wisdom, Olesya carries her family’s ancestral gifts with devotion and gratitude. Her sessions often weave Rune Oracle readings, Core Energetic Therapy, and Shamanic practices, guiding each person toward wholeness, empowerment, and divine alignment.
