This isn’t just “eat better, move more” crap.
This is expert coaching, daily accountability, and intelligent data tracking—all wrapped up in 8 weeks of focused action that’ll leave you feeling unstoppable.
Choose your focus:
Fat Loss – without starving yourself or hating your life
Performance – wanna train like an athlete? You need to eat like one
Muscle Gain – cos BIGGER is better 
Overall Health – energy, sleep, resilience = mood & vibes up 
Recovery – everything you need to recover from injury & be the ultimate comeback kid 
(coming soon)
You pick the goal, and we’ll tailor the tracker and targets to you. You’ll get daily support (and banter 
), plus expert advice from the Ninja to keep you consistent and clued-up.
Each day, you’ll spend five minutes filling in your tracker—because we’re all about results.
At the end of the challenge, we run fitness tests, take body fat measurements, and wrap it all up with a full data analysis from me. You’ll get clear feedback on your progress and my expert recommendations on what to do next.
Like all things CrossFit, it’s totally scalable. We’ll meet you where you are, from ‘never been a gym person’, to ‘I’m going to the Games’ and everything in between.
” Doing the challenge with Hayley has been absolutely fantastic!
I’ve done 2 consecutive challenges now to focus on different things – the first to lose body fat after having my little girl and the second to rebuild my performance.
On the first challenge I lost over 10% of my body fat thanks to Hayley’s support and guidance, plus there is a real sense of community and you feel like you and all the other challengers are on the journey together which spurs you on.
Hayley provided some really great tips for how to get a bit more protein into your day, how to drink a bit more water and how to do a few more steps and it is these small changes that make a big difference.
Because there is one new aspect to focus on each week it doesn’t feel overwhelming and each week builds on the previous to end on a set of really well rounded practices which I still implement into my daily routine now.
Hayley worked really closely with me on the second challenge to make sure we figured out what my maintenance calories were and how I could tailor my meals to match my goals.
I would absolutely recommend doing one of these challenges to anyone – you get such a sense of achievement at the end, you are supported by Hayley and the other challengers and it creates healthy habits to last!”

Hi, I’m Hayley Field AKA The Lifestyle Ninja…
Hey, I’m Hayley, the Lifestyle Ninja, and I can help you design the lifestyle you want around your business.
I work best with female founders…because I understand that running a business brings its own set of unique ‘challenges’ to our health, our relationships and all the other shit we’re expected to balance on a daily basis.
I’m here to help you bridge the gap (or chasm) between where you are now, and where you want to be, by putting your health at the centre of everything.
Why?
Cos you won’t get very far without your health.
When I first started out as a Nutritionist, I very quickly realised that you can’t untangle your health from all the other shit you have going on.
You KNOW what you should eat, that you should exercise, that you should relax. It’s not a knowledge problem.
It’s about having the ability, the mindset, the capacity and the BELIEF to do those things consistently.
That’s what I’m here for.
Every client I came across would have a different issue- not sleeping well, not managing stress, juggling too many roles- business owner, wife, mum, daughter, carer…
Which is how I ended up with my ‘unique’ set of qualifications 🤓…to TRULY sort all the shit that’s holding you back and help you to achieve your version of success.

Frequently Asked Questions
Do I need to be ‘fit’ already?
Absolutely not – the challenge (and fitness tests) can be scaled to your level, and a Coach will help you with this. There is ALWAYS a version that you’ll be able to do, that will be appropriate to you.
Will I have to dedicate lots of time to this?
We all lead busy lives – the challenge is designed to fit with your lifestyle, and there’s always A version of the habit you can do.
All the videos are under 20 minutes long, and if you don’t have time to watch those, there is a weekly “What do I need to do this week?” video that is always around 5-8 minutes long.
You’ll have a tracking spreadsheet to fill in, but if you do it daily, it’ll take less than 5 minutes.
I will be in the Whatsapp group every single day, so you can get your questions answered as quickly as possible.
Will you give me a list of foods I’m not allowed to eat?
Definitely not! The challenge is based on principles, which means you’ll get guidance on how to tweak them to fit with your lifestyle and preferences.
You can get a great result without feeling miserable about what you’re eating!
But does it work?
