I’m Petrina (or Trainer Trine), the face behind OAK.fit. I run a fitness business with one simple mission: to help people feel stronger, move better, and build confidence at any age or stage of life.
With over 30 years participating in the fitness industry, I decided to turn my passion into something tangible that I could share with others.
I love learning and continuing to grow, and my qualifications reflect that.
I work with a wide range of clients — men and women, younger and older — including those managing injuries, starting or returning to exercise, or simply wanting to improve their strength, fitness, mobility, and overall wellbeing.
Ladies if you are pre, menopausal or post then you are one of my special clients that I love to help through this challenging time in your life.
My key focus is on functional fitness, long-term health, and creating a welcoming, supportive space where you can genuinely feel that “Yes, I CAN do this!” energy. Surrounded by like-minded people, we enjoy a positive, social environment while working towards individual health goals.
I offer group classes in conjunction with The Change Project - Toowoomba Region for just $5 per session — fun, full-body workouts that build strength, cardio fitness and mobility, all in under an hour.
I also provide one-on-one personal training and 6-week programs for those wanting a more personalised approach.
You’ll also find me at parkrun every Saturday morning — my favourite way to kick off the weekend (with a well-earned coffee afterwards ☕?).
