Sasha Temaru 

Founder and Head Trainer

With a sporting background and a passion for physical activity I was destined for a career in the fitness industry.  Over the last 4 years I have worked as a trainer in commercial gyms around Wellington. I have been lucky enough to work with a number of different groups and individuals, I have been a part of many journeys and have witnessed many incredible transformations.

In 2017 I created Grind Health and Fitness, a business that was inspired by the 3 things I love most in life;

  • Family;

  • Fitness, &

  • Fun.

I wanted to create an environment where people from all walks of life could come together and train in a fun and supportive environment. As much as that’s a big part of Grind I also live by the notion that ‘nothing great in life ever comes easy’. My training style will challenge you, I will encourage you to push past your boundaries and comfort zones, I will test you physically, mentally and emotionally but just know I will have your back, the team at Grind will have your back, now its time for you to back yourself, take the leap and I promise you won’t regret it.

Toni-Faith (Fizz) Temaru

Boxing Trainer

Sport, health and fitness has been a massive part of my life from a very young age. Growing up I competed in a number of different sports, some of them at representative level. My passion for health and fitness led me to Otago University where I studied a Bachelor of Physical Education and a Bachelor of Arts majoring in Psychology. I have always been interested in the mental side of sport and fitness and I am a true believer that with a strong mindset you can achieve anything.

In 2015 I decided I wanted to challenge myself and try something new, I signed up for a charity boxing event and 14 weeks later I stepped into the ring for the first time. With a victory under my belt I wanted more and since then have gone on to compete in 2 further corporate fights and more recently I have taken a step up into amateur boxing.

Boxing has taught me you can always be fitter, faster and stronger than you think you are so you have to find a reason to keep wanting to be a better version of yourself. I am excited to share the skills and knowledge I have learnt through boxing and sport in general, to provide you with challenging but fun workouts.

Boxing achievements:

  • 3 Corporate boxing fights

  • 2018 New Zealand North Island Novice Golden Gloves winner (60kg)

  • 2018 Australian Novice Golden Gloves winner (60kg)
