Any woman has the ability to accomplish great things, but first she must believe in herself.  Once she starts achieving her goals, she will begin to inspire others around her to make positive changes in their lives too.

Being a Strong Woman isn’t just about going to the gym and lifting weights.  A Strong Woman is a positive role model.  Knowing how important good nutrition is she supports and encourages family and friends to fuel their bodies with healthy, nutritious food and to be active so they may lead longer, fuller, healthier lives.


Hi! My name is Sarah Martelli. 

I live with my husband, 3 kids, our dog and chickens on a dairy farm in Reporoa, New Zealand. 

After my recent illness I was determined to get my life back on track for myself and for my family.  I wanted to lead the most fulfilling life I could, and so my own journey back to health began.

Having experienced what positive healthy changes did for me, I wanted to inspire other women to become stronger versions of themselves. So I qualified as an Advanced Personal Trainer. Now I run ladies group fitness classes and one on one personal training sessions through Strong Woman Fitness, and have recently launched the Stronger You online fitness platform.

I know that if you are determined and believe in yourself, you can achieve your goals with the right support. Contact me, I would love to help you become the strongest version of you!
