About Onelife:

Onelife is a boutique, holistic, and integrative health coaching service striving to provide women with a high level of coaching to provide the education, inspiration, and support in finding their best health so that they can live their best lives, and share this with others in their community.

I don’t see any one sized approach that works for everyone – we are all as unique on the inside as we are on the outside. By working with only a small number of people at any given time, I am able to put the time, energy, and attention into thoroughly assessing each client and determining the best approach for that precious person. I then follow through by coaching them through the process, empowering them to take control of their own health and well-being.

I love to work with ladies from all walks of life, wherever their starting point. Whether that means assisting them in improving symptoms of chronic health complaints, or optimizing their health in order to continue to perform at a high level, for as long as possible.

Meet Shelly:

I first entered the fitness industry in my very early 20’s, aspiring to share with the others the experience of improved physical, mental, and emotional health I’d gained through discovering exercise in my teens.

Not an “athletic” or “sporty” person at all, I had experienced my fair share of depression and poor health by this time, and discovered a love of moving my body, improved confidence, positive role models, a natural alternative to antidepressant medication, and most importantly at the time, a place I felt I belonged, when I began attending the local gym. After beginning as an aerobics and gym instructor in my home town of Napier, I quickly moved into personal training a year after moving to Christchurch. I wanted to offer the people I worked with more – more individualised programmes to meet their goals and needs, more service, and more support. This ultimately lead to more results for my clients, and more job satisfaction for me. During this time I also competed many times both regionally and nationally in bodysculpting. This improved my ability to set and achieve goals, overcome my fears, and further improved my confidence. Noticing that I again experienced positive changes in my heath; less gas, bloating and constipation and better energy, I also began to make the connection between what I ate and how I felt. Another piece of the puzzle…. Taking time out to have children and raise a family, I decided to take the opportunity to learn more about some of the underlying causes of some of these health challenges I’d experienced, which are so common. It seemed to me that the human body is designed for perfect function. And doesn’t malfunction for no reason. I couldn’t understand why a person who seemed to have an awesome life could feel that the world would be better off without them. And I also suspected that although there are many common features, what worked for one, would not work for another. So I set about studying Optimal Health and Fitness through Practical Nutrition and Holistic Lifestyle Coaching with the CHEK Institute and more recently Functional Diagnostic Nutrition which is a type of detective work using functional lab testing to identify common imbalances and malfunctions which contribute to and correlate with many of the symptoms people experience.

  • I now get to share what I’ve learnt, and its my mission to empower other women to overcome their own health challenges, so that they too can experience their best health.



I just wanted to say thank you for everything that you have done for me these past 6-7 weeks. I wish that we could have continued our sessions.

You have helped turn both my life and health into a much more positive and balanced journey. You have given me tools and taught me lessons that I can continue to use and develop throughout my life- I will always be grateful for meeting you.

“My name is Jean Southorn, and I am 25 years old and running a small personal training business. For years I have worked hard, studied, and was always on the go without looking after myself. I am a very sporty person- I love to play netball- however I have not enjoyed a game for the last 5 years. I have always felt tired, fatigued, and could never get my mind into the game no matter what I did. As a health professional I thought I knew how to look after myself. I was fit and always trained hard. My first year running my business I was working long hours six days a week, and every day I felt dizzy, had constant hot flushes, and my mind was always clogged. Everyday I became more frustrated because I didn’t understand why I was feeling like this. I decided to do something about it and got in touch with Shelly.

The first week of spending time with Shelly she gave me tools that gave me instant relief and understanding. Feeling different within the first 2 weeks made me excited and I couldn’t wait to see her each week.
Having spent the last 3 months working with Shelly and I can say I feel like a teenager again! This is coming from a 25year old female health professional! I am grateful and so pleased I have experienced Shelly’s expertise because I think and look back at how I used to feel for all those years and wonder how I survived. I have more energy, my skin is looking the best and I feel calm and level. Shelly has also educated me with great exercises which I have benefited from, and also pass onto my own clients


Dearest Shelly

How do I start to say thanks to you? We have been in each others lives for countless adventures and fun. You have been a informed outsider who has supported me with honesty and kindness. I would not know myself as well as I do without you reflecting back to me my true self. Thank-you. I understand the lesson, and in the immortal words of Piri Weepu “I got this!”



“Shelly has a wealth of knowledge and expertise in personal training, nutrition and health. Her holistic approach to exercise and well being has helped to shape my current running program and has ultimately enabled me to achieve my goals!”

“Dear Shelly

I wanted to write and say how grateful I am to have had your help and support this year.
You have helped make a huge difference in how I look and judge myself.
I think about your words “a healthy relationship with food”, I believe that I have a foundation for this because you have steered me in the right direction and I trust your navigational skills in reading the unfamiliar waters and me.

Thanks-by the way the truffles are amazing-it’s time for your cookbook please-plus if you have time please send recipe especially the white and coconut ones-yum.:-D

Shelly is more than just an exercise expert! She looks at the “whole” you and guides you in the right direction. She isn’t pushy and is considerate of your beliefs and life situation. I highly recommend Shelly to anyone who wants to live a healthier lifestyle that fits with you and your family’s circumstances.
