Seasonal Yoga

Yoga aligned with the changing seasons

What is Seasonal Yoga?

Seasonal Yoga is a “yang” style yoga practice which is designed to align you with the changing energies of nature and the seasons. The concept was created by Julie Hanson and Sue Woodd in 1995 as an antidote to the stress and anxiety of modern life. It combines Yoga, Qigong and Tai Chi with traditional Chinese ideas about harmonising the energy of nature which is both around us and within us, bringing balance. What is practised in the classes changes each season, with the energy of nature. I came across Seasonal Yoga a few years after starting teaching and became increasingly fascinated with this amazing practice – something clicked! It also fitted seamlessly with my previous trainings. Seasonal Yoga now informs all the classes, workshops and courses that I teach.

2023 - 15 years of teaching Yoga!

I can’t quite believe it, but I’m in my 15th year of teaching yoga and some amazing people have been with me for a big chunk of that time! It’s been quite a journey so far. I feel blessed to have been around Yoga as a youngster (thanks Mum and Dad)… and then later found my calling in becoming a teacher. To celebrate and mark this I’ve collected some stories and some pictures from across the years…

yoga teacher Rachel

"...Rachel is a unique and exceptional yoga teacher. I was introduced to her when I most needed a change in the style of yoga I was used to and her approach was ideal. The seasonal way in which she teaches allows an understanding of our own bodies and a greater awareness of the rhythms of the natural world that surrounds us and is so often overlooked..." - S.J.

Fundraising from yoga


One of the highlights of teaching on Zoom has been the charity fundraising Yin Yoga class...

“I was thinking about yoga today and the difference it has made to me. I really look forward to your class and always come away feeling calm and relaxed.For me, yoga has given me space to breathe and learning to breathe properly' has helped me put the brakes on my anxiety. My own practise is intermittent at home and yet I find myself doing random bits of yoga during the day and it works. I can breathe more deeply and slow down more easily. So, thank you for that.”

Online Studio

We have a Seasonal Archive of video classes available to watch

As well as the live classes, Rachel has a video library of recorded classes for each season, mainly yang classes and some yin classes. More recently Rachel has started a short series of Seasonal Qigong classes which run about 30 mins. These are available separately from the Online Studio.

The Online Studio started in 2020 when the Covid 19 Pandemic hit, everyone went into lockdown and no live 'in person' classes were being taught. Rachel started teaching live classes on Zoom and made a few videos for students to practice at home. As the lockdowns continued, more videos were made until we have a yearful of seasonal videos.

Events and Workshops

Various workshops and events are held throughout the year...

Events and workshops

Workshops are run throughout the year and concentrate on a particular aspect of each season.

If there is a particular subject you would like me to run a workshop on please let me know.

What does a workshop involve? Most of my workshops run for 3-4 hours in a morning or afternoon. Do we practice physical postures for all that time? Definitely not! Workshops will offer a variety of practices including breathwork, meditation and information. I also generally allow time for chat and a cuppa together.

“I went to two of Rachel's classes at the IYN festival in 2017. Amongst many impressive teachers, her classes stood out. I found my mind calmed and my body opened by one yin and one hatha session, both of which were taught with compassionate and generous spirit. Thanks Rachel.”
