ALEX - Owner & trainer


Hey I’m Alexandra Offen (Alex). I live and breathe health and fitness and am a big advocate for creating a healthy and balanced lifestyle. After high school, I went on to Double Major in Physical Education at Otago University. I then spent 1-2 years living in and visiting Australia, Canada, America, and Mexico. I coached internationally and in New Zealand for Regional and National level swimmers.

I then met my fiance Jonny . We decided to embark on a health and fitness journey together. That journey was opening Central Fitness Cromwell back in 2017. With the support of our incredible team we have created a space and a community we are very proud to be a part of.


We know how important staying healthy, fit and positive is for our well-being and we love that you have chosen to be a part of it, whether that be in the incredible Central Fitness Facilities across the South Island or with us online.

JONNY - Owner & trainer


Hi, I'm Jonny Roberts. I call Cromwell home and this is probably because of the friends I have made here.

So why the gym you ask. When I wasn't able to do all the things I loved most, I was at the gym. This place is my happy place.

There is an element of self-improvement about health and fitness that is addictive. This doesn't mean just lift something heavier, but finding out how to do it better. More importantly, this is across all platforms. Mentality, nutrition, movement, attitude, even connecting with people.


This is why it is so important that we stick together, create an online community and fight this fight together.

CHRIS - Cromwell small group fitness instructor

Chris Foster has been a member of Central Fitness Cromwell since almost the beginning!

He has been a regular - often training 5-6 times a week. You could say he is obsessed but in a healthy way!

He is now studying to become a qualified trainer. Chris is gaining experience and expanding his already impressive knowledge base by running our FuncFit classes. If you haven't had a chance to try his class yet, this is what one of the regulars had to say:

"I really enjoy coming to FuncFit, Chris has gotten to know me well and knows how to push me. Every class is different and I always leave feeling proud of myself and what I have achieved in his classes, thanks Chris"- Elle Tredinnick

MO - Cromwell Gym Manager

Monica Penniall, more commonly known as Mo or Monnie was a dedicated and loyal member of Central Fitness, before becoming a part of the team in 2019.

We were so impressed by her constant drive in the gym and commitment to her overall health and well-being. We have witnessed her transform herself both mentally and physically.

Since joining the team Mo has inspired members to do the same by focusing on becoming "strong, not skinny". We love this philosophy and are stoked that this is the message she is sending!

Monnie is often sprinkling her positive energy, sharing her own gym experiences and offering her overall good chat. Don't be afraid to ask her for a spot she is pretty strong, don't let her chill vibes fool you!

HANNES- Picton Gym Manager

Hi, my name is Hannes. I am a friendly South African in the Central Fitness Team!

For as long as I can remember I have always been involved in sports. This led me to study and complete my Honours degree in Sports Science. I've been very fortunate and have worked in the fitness industry for more than 10 years in South Africa and internationally. I have had the privilege of working with many professional athletes across various sporting codes such as running, cycling, javelin, squash, tennis, and golf, as well as training for triathletes and much more.

My specialty and motivation for training revolve around body movement mechanics and injury prevention; getting the body to move more economically. I particularly enjoy and promote mobility and functional training. I’m a huge advocate for movement, no matter your age or fitness level, and I firmly believe a healthy body stimulates a healthy mind.

Be healthy, you deserve it!
