The Full Story


Luna Castilho is a Registered Yoga Teacher, Certified Breath work, Pranayama teacher, Sound Healer, Certified Personal Trainer (NASM), Group Fitness (AFAA), Nutrition Coach and Indoor Cycling.

She did her yoga trainings at Pure Yoga and Prema Yoga Institute, giving her a background in Vinyasa with roots Ashtanga and Iyengar alignment, as well as Hatha yoga practice, philosophy and pranayama techniques.

On her strength classes and personal training sessions expect tons mobility, plyometrics, calisthenics, weights, kettlebells, power moves and maximal strength.

On her private yoga classes or personal training, She will work together with you to tailor a plan that work for your goals and needs.


Luna grew up in a small beach town close to Rio de Janeiro, Brazil where she grew up surrounded by nature, hiking mountains barefoot, going to the beach, surfing, exploring the jungles and playing all sorts of outdoor sports.


For nearly 20 years in the Fashion industry working as a fashion model, she spent most of her life trying to constantly adhere to a certain “beauty standard” set forward by the fashion industry. Unhappy with how she felt, she discovered her life’s purpose: to help others embrace their body and find their power within.


Practicing yoga for many years she started as a strength coach, but she found in yoga an opportunity to unite the physical and the spiritual practices. She considers yoga an opportunity to heal, connect and remember our strength  within.


When taking classes with her, you can expect powerful flows combined by mindful contemplations and grounding experiences, as well as somatic release, working the body, mind, soul and spirit.



My purpose is to help you find you power within.

"Have you ever wondered what it would be like to be taught by an åactual angel? Because that could be your reality here!! Luna is a
*goddess.* She is the embodiment of yoga in that she is a perfect balance of fitness and spirituality. I love that she themes her classes to help you find an external purpose but also offering the option to just do what fits your needs that day/season. She is welcoming to all levels of students and focuses on creating a smooth flowing practice that will leave you feeling physically and emotionally balanced. After a long hiatus from practicing and teaching yoga, one class with Luna has inspired me to prioritize daily practice again!"
