I’m Rachel Aust
Nutritionist, strength coach, and creator of The Power Curve Method.

With over a decade in the industry, I help women bridge the gap between fitness theory and sustainable results. My work blends clinical nutrition, biomechanics, and behavioural psychology with no fluff or fads.

Whether you’re here to build muscle, reshape your body, or repair your relationship with food, I’m here to guide you.

 

Let me help you create a
healthy lifestyle you love.

Ready for the “healthy lifestyle” to feel a lot more balanced and actually healthy?

When you set up sustainable lifestyle habits that you’re able to stick to consistently without flipping back and forward between different diets and trying every exercise regime under the sun you won’t have to work so damn hard to have healthy habits that stick and a body that you can actually feel confident in.

Whether you're just getting started, or you've been at this for a few years, I'm here to help you create your perfect lifestyle through simple strategies that actually work!

 
 

With my Premium Coaching Program you can completely change your body and life from the inside out. I will personally design a plan that works for you, your body, and your health concerns. I want to help you look forward to healthy living, not dread it!

I know that exercise and nutrition can feel complicated and stressful...but I promise you it can also be simple. Yes, there’s some magic that needs to happen to build your ideal lifestyle, but I’ve got your back! 👇

My unique Mindset Coaching Program™ will help you combat the excuses and resistance that have popped up every time you’ve tried to recreate your lifestyle previously and dig into what’s been holding you back. Limited spots available.

Let’s get started!
