Hi, my name is Petra Lewis and I have been in the fitness industry since 2000. Starting as a tennis coach realizing how much I enjoy the fitness aspect and helping people to reach their fitness goals. As a result, I became a Personal Trainer. Later I started to have lower back pain and various heath issues which led me to discover the healing power of YOGA, PILATES and QIGONG.
I have completed 200h Yoga teacher training with The Kaivalya Yoga Method Academy and currently studying another 200h Vinyasa & Yin Yoga with Bristol School of Yoga. I love how Qigong and Yin Yoga compliment each other with the healing benefits as I am a strong believer in the bodies self-healing powers through mindfulness, breath, movement, working with meridians to improve the free flow of QI (energy) in the body. I believe with our busy modern lifestyle it’s more important than ever to take time for yourself and there’s no better place than a Yoga mat to reconnect through movement and stillness.
I am passionate about making a difference in people’s lives by improving their health and fitness, seeing positive changes, and finding comfort within the discomfort of pain, whilst building strength in body and mind.
