We Are SiSU

Pronunciation /ˈsi ː suː /

Strength of will, courage, and resilience in the face of adversity.


1920s. From Finnish sisu.


Sisu is a unique Finnish concept. It stands for the philosophy that what must be done will be done, regardless of what it takes. Sisu is a special strength and persistent determination and resolve to continue and overcome in the moment of adversity… an almost magical quality. It is a combination of stamina, perseverance, courage and determination held in reserve for hard times.

Together, we are SiSU.

Our Story

Our story starts with a friendship that began in a local gym, years ago.  Very quickly, we identified a common interest – helping people prioritise their health.  We believe good health is the foundation to a better life.

A dream was soon born to combine Alex’s background as both a physiotherapist and pharmacist, with Agatha’s background in personal training, health coaching and human resources. We wanted to create a holistic wellbeing space that could help every member achieve their individual health goals.

Fast forward a number of years of relentless searching,  in late 2020 our dream became a reality.  We are incredibly proud to offer a community focused facility, where a holistic approach encompasses all that we offer.  We hope that with our collective experience and combined desire, we will achieve our mission to coach, motivate and inspire each member of our SiSU community.

We’re committed to running our business in alignment with all of our personal values and that includes doing our bit for planet earth.  With this in mind, anything we do at SiSU undergoes an environmental impact assessment, to ensure, where possible, our products, processes and systems are as kind to our earth (land, people and animals) as possible.

We can’t wait to welcome you into our SiSU community.
