To become the go-to fitness provider for the 40+ age group in the Hunter region. To change the perception that ageing equates to a loss of strength and movement. To provide exception training solutions that enrich people’s lives, regardless of their current age or circumstances.


At Renew Fitness we believe that being fit doesn’t have to be time-consuming. That training and getting strong are about enriching your life, not dominating it. Exercise should restore movement, reduce pain and build you up, rather than break you down.

In essence, it is about QUALITY OF LIFE. Whether you’re:

~ Juggling work with young children

~ Working full-time with a busy social life

~ Semi-retired with travel plans and grandkids to chase

We have the solution for you.



STRENGTH: Strength is the master quality. Without it everything is harder, with it everything is easier. So we will train our bodies and our minds to be strong.

COMMUNITY: None of us has to do this alone. Lean on a community of like-minded individuals because it will make your journey more enjoyable, fulfilling and successful.

COMMITMENT: Without a true commitment to a cause or goal progress cannot be made.

RESPECT: Respect the rules, respect each other, respect your body.

BALANCE: What’s it’s all for if you can’t enjoy life as well? Train hard, eat well but also let your hair down, party, drink, sleep, relax and indulge because life is too short.

FUN: Stop being so serious. We’re swinging kettlebells not saving people from a burning building. Training should be fun, not something that stresses you out


Expect to feel supported and encouraged from the moment you walk through the door. Our private studio in Mayfield is the perfect place to begin the journey of rediscovering your fitness or perhaps getting fit for the first time.

What clients are saying...

Mary Ann

Mary Ann

Pete has given me functional movement that I believed I had lost forever. 

"It seems too easy to say things like “I can’t recommend him highly enough” and “Pete has changed my life” but, glib as they seem, they are true.  He has given me real strength, fitness, endurance and a pleasure in physical achievements that I’ve never had before. He has understood, encouraged, challenged and motivated me.



Thanks to Renew, I'm becoming the person I want to be!"

"Pete has been the motivation I needed to start chipping away at, no, smashing 50 + years of relentless weight gain and apathy. I love that I can start my day with a gym sesh at 5.30. I love the feeling of walking out of the gym, knowing that I've made a really positive start to the day. I have such amazing energy when I get home and get the children ready for school.



I believe I have done better in one month with Peter than I have done training with any other trainer or coach in Newcastle.

"Peter really knows his stuff, he broke the swing down in a way that anyone from beginner to an advanced pupil could understand get something out of it. He really knows how to motivate and drive me to do better with each and every training session that I approach.Highly recommended"



I have no trouble keeping up with the energetic 5 year olds that I teach on a daily basis and sometimes they can't keep up with me!

My name is Robyn I'm 60 year old and over a period of 12 months training and learning from Pete I have lost 25 kg and 4 dress sizes. But that is not the reason that I have continued training. Through training I am fitter and healthier than I have been in over 30 years and have more knowledge about nutrition than ever. My blood pressure is now normal and my resting heart rate is good for someone half my age.



I highly recommend Renew Fitness. it's not about "image" it's about living well.

Pete has changed my strength and mobility in more ways than I can count. My confidence and self esteem has improved out of sight! As a 55 yr old in reasonably good health I was struggling with my mobility, especially getting down off the floor or out of a pool without support. This frightened me a bit being a nurse I knew my mobility was paramount. Peter has guided me, pushed me to the point where I'm now totally cool with getting up and down and I do much else ..I take on things I would not have considered 12 months ago .This has been a game changer ..a life changer



I'm achieving my goal & getting stronger & fitter every week. As a bonus my overall shape has improved & I'm a much happier version of myself.

I've been training with Peter since July 2016 & absolutely love it. My goal was to become fitter & stronger as I was approaching 50. Peter's approach to his clients is real & evidence based, he works with everyone individually tailoring each session to the participants. I can highly recommend Renew Fitness if you are looking for fitness personalised to your needs.



Pete is just the right mix of positive energy that makes it easy to turn up to the gym.

Pete is passionate about helping people get healthier and stronger. I love the small group sessions and the different things that Pete is always introducing to keep it interesting. He really knows his stuff and I cannot recommend him highly enough.



Only regret is not picking up the phone and calling sooner.

Couldn't be happier with the results I've achieved with Pete and Renew Fitness - much fitter, healthier and stronger in a relatively short time. Small groups with well structured and varied sessions keep it interesting and fun.

Sacrifice and Reward

Something to think about this Sunday: Sacrifice and reward. Long term fat loss relies heavily on these two things. You will not achieve it without striking a balance between the two. The good part is Read more…

fat loss takes time focus on the process not the result
