The Affirm Story

Founded in 2017 by Personal Trainer, Health Coach and Group Fitness Instructor Diana Trenerry, she met so many people frustrated with their struggle for fitness with high stress, low self-priority, and chronic disease risk.
The ethos of the Affirm Body Fitness is based on a strong belief that fitness and health are intimately related, and that the small regular habits, not just fitness training, have a big long-term effect on these, in either a positive or negative way.

Diana’s mission is to positively change the way we think about quality long-term health, employing science-based strategies so that our clients find their way eating and exercising better, to maximise their quality of life.

Regain vitality and confidence with better strength. Science has proven that lifting weights regularly is the only way to slow or stave off osteoporosis and muscle atrophy. Fortunately, it also improves muscles for strength and shape at any age.

Naturally, nutrition and exercise harmonise. But using epigenetics gets it perfect for you. Think also of your unique and optimum biorhythms, sleep patterns, and hormonal and stress management. We can support your success with your personalised epigenetic app.

Expert in both precision Pilates and higher-level core loading, we deliver at the intensity your body needs so you improve waistline, balance, sport performance, and manage injuries like lower back, hip, knees, and shoulders.

We program for your best posture, with attention to improving joint mobility/stability and tissue flexibility. Better posture allows good movement and helps reduce, manage, or prevent injuries.

We use safe movement patterns that work fascial lines and muscles together, just as you do in life. Enhancing strength, flexibility, posture and movement for sports performance, home life, and injury management.

We are expert delivering precision fitness to just one, couples, family, or friend groups, and for small classes. You can choose your training style to suit your schedule, budget, just you or with others, and those especially important fitness and health goals.

I would recommend Di as she is fun and challenging and does different exercises than my usual routine.  I have seen huge improvements to my health and fitness since 2018, and it is all thanks to Di!

Before I started at Affirm, I was challenged with sport injuries, weight, and flexibility. Since being coached by Di, I have better flexibility and understanding of foods. The workouts are fun, challenging, and personalised. I recommend Di for any goal, ability, or fitness level.

You Are Not Alone!

As a Coach, we so often hear these comments:

  • “Why does my weight increase just ‘looking’ at food?”
  • “Been on heaps of diets, but now I am heavier than I have ever been.”
  • “How come I train so hard every day and I don’t see any change in the mirror?”
  • “I’m going through that mid-life shift, and methods to lose weight when I was younger just don’t work anymore.”
  • “I have been diagnosed with Diabetes type 2, so it’s too late for me.”
  • “My arthritis makes moving painful. What can I possibly do to get fitter?”
  • “I feel so frustrated with my weight and the health issues and pain it is adding to my life.”
  • “I am so stressed, busy and overworked, I just don’t know how I can fit any time in for me.”

Have you thought that maybe you are dealing with the symptoms but not the cause?

Why Train With Us?

Have you ever had a “big” weight loss on a 12- week challenge, or a weight loss program, only to gain it all back and potentially more?

‘Research at Monash University states repeated dieting, or yo-yo dieting, may lead to weight gain because the brain interprets these diets as short famines and urges the person to store more fat for future shortages.’

We all know that exercise and diet are a large part of the equation to reach the ideal of optimum health.

We all want and need:

  • Good muscle mass, (providing strength and fat burning capability)
  • Good bone density, (for good posture, reduced pain and aches, reduced risk of debilitating osteoporosis),
  • Cardio-vascular health, (strong heart and lungs for resilience and vitality)
  • Good mobility, (to feel younger and capable)
  • Injury prevention and management of existing injuries,
  • Prevention of chronic disease

But to maintain your best fitness and health, whatever your age, other key variables may need addressing for your success.

Therefore, combining Health Coaching with Fitness Training is an amazing way to find, and keep, the best version of you!

Kaye Dalus

Diana has been my coach for over 2 years. With her help I have been able to stabilize my lower back to allow me to play weekly tennis fixtures which was my first goal. Since starting with her, I’ve achieved so much more. I have more energy, flexibility, strength and staying-power. She has so much knowledge and is able to gauge when to push me to get me to peak condition. A wonderful coach! Top shelf!

Heather Wentworth

Having had a few different fitness and health Coaches over the years, Diana is an absolute stand out professional in every way.
Her ability to ‘listen’ to what my body is saying and her experience and vast knowledge she intuitively knows how far to push me, and when to pull back to avoid injury.
Couple that to her holistic knowledge and I am so privileged to have her as my Coach!
Can only say that if you are lucky enough that she has the availability to fit you in, into her busy schedule grab the opportunity with both hands, as you won’t find a finer Coach.
