BRAD ROACH – Flexa Studio Yoga Instructor/ Flexa Studio Trainer

Experience and philosophy: Over the past several years I have been working between the US and the UK , originally starting as an outdoor education coach and primitive survival instructor, this roll developed to teaching Yoga, Calisthenics and Archery on summer camps. After travelling over 30 states and learning valuable yoga and meditation skills from Native Americans, My passion for Yoga began after suffering a ACL tear and a dislocated knee. After having surgery and being told by doctors that there would be an 18 month recovery period I started practicing dynamic yoga and within 3 months my knee was stronger than it was before the injury. Seeing these improvements in myself has motivated and fueled me to pursue helping other people rehabilitate injuries and achieve their own ultimate goals, Physical and or spiritual. After building and establishing Yoga classes in England over the past 2 years I decided to continue my travels which brought me here to New Zealand and in turn brought me here to Flexa Clinic.

“Notice that the stiffest tree is most easily cracked, while the bamboo or willow survives by bending with the wind.”

Yoga and meditation practice.

Since hiring Brad as my trainer I soon saw a huge increase in my strength, stamina and physical ability. Brad took the time to explain everything thoroughly and set me challenging but achievable goals. He has helped give me the motivation and confidence to push myself further. I feel I have really benefited from working with Brad and would not have progressed as far in such a short time without him. I would thoroughly recommend Brad’s services to anyone who is looking for a personal trainer.

I am originally from Brazil, I’ve been working in the health care and fitness industry since 2005. I decided to come overseas with the purpose of learning and exchanging knowledge.
