What's SO *Different* about Fitness & Nutrition for Petite Women, you ask?

Well, you’re about to find out it goes way beyond the measuring tape, baby cakes.

Because here’s the thing… the more you understand WHY your miniature bod requires a slightly different approach, the easier it will feel to maintain a little but fierce physique.


Without the lowdown

… you’re screwed.


We’re about to re-wire everything
you think you know about
fitness & nutrition...

(and answer this honestly—no judgement here)

Is where you're currently at with your body... a place you would be absolutely ecstatic to stay in?


Lemme get a head nod if this sounds about right:

Things could be BETTER.

Because right now, getting that snatched waist is a struggle (to say the least). And you don’t understand why the scale isn’t budging despite the fact that you already eat so little.

You open up Instagram every single day to see taller women absolutely killing it.

They’re consistently filling your feed with pics of their lavish higher calorie meals, and you’re just over here like….


If most days seem to end with uncomfortable bloat, constant fatigue, & insatiable hunger...

If your mornings typically begin by stepping on the scale devoid of any significant progress...

If month after month comes to a close without hitting your body composition goals, and you’re constantly telling yourself next month is it...

Next month is going to be my month. The month when I really crack the whip for good!

But you’re stuck in the same vicious cycle of yo-yo-ing

And if you’re getting so freaking sick of waiting, of feeling unstable, and of living in this constant limbo of “will this new diet actually work?”...

Then I’m here to break the news to you:


Does our effort make a difference? Of course.

Is it the only thing that matters? Absolutely not.

Rather than throwing spaghetti at the wall and hoping it sticks,

we need to do what’s effective — for our body size.



The Funsized® Formula

  Enroll in Course

A mini [but mighty] online course to crack the code on your petite physiology so you can ignite your metabolism — without sacrificing carbs, your hormones, or your sanity.

Full Stop🛑

I'm not here to promise quick fixes or "lose 10lbs" magic tricks.

With the Funsized Formula, you'll absorb essential nutrition and fitness wisdom for petites, sprinkled with some incredible mindset shifts that will set you up for consistency and enjoyment in your healthy lifestyle — and, therefore lead to fat loss and muscle gain.

Think of this course as the foundation of a house. Without a sturdy base, that house crumbles, right? Well, just like that, without this strong foundation, your results might not stick around for long.

Together we'll looked at ways of strengthening your sense of control and empowerment, of generating hope and excitement rather than fear, of taking control of stress and steering your life, rather than feeling like it's steering you.

With the insights you'll gain from this course, you can reframe your perspective and take informed action to change the outcome.

Consider it a "user manual" for your petite physique, empowering you to take the reins of your own well-being journey! 📖🌟🏋️‍♀️

Frequently Asked Questions

When does the course start?
The course begins the moment you enroll! "The Funsized Formula" is a self-paced online course designed to fit seamlessly into your busy life. You have the freedom to decide when you want to start and when you want to finish. Some ladies dive in and complete the entire course in a single weekend, while others dedicate a month to devouring the content. And hey, if you prefer to savor the information gradually, that's totally cool too! If you opt for a steady progress approach, I recommend completing one module per week. This way, you'll have that wonderful feeling of "graduating" from the course in just one month!
How long do I have access to the course?
How does lifetime access sound? After enrolling, you have unlimited access to this course for as long as it exists - across any and all devices you own. Since my work is research & evidence-based, you'll also get all updates I make to this course in the future (without any additional fees)
How much weight can I expect to lose?
I don't sell shiny "lose 10lbs" promises (although I could & have the client results to back that up). I lead this course with what I know in my core to be the true foundation of a health lifestyle with LONGEVITY; understanding how nutrition + fitness affect your petite bod on a deeper level and developing a unique approach that fits your stature. Whether you're aiming to lose weight, build muscle, maintain your current shape, or simply boost your confidence in your healthy choices, I'm confident the things you learn here will connect you with your petite body's needs like never before — which is the necessary foundation to build in order to achieve long-lasting results. Think of this course as like a prerequisite to long lasting results.
Does this program include meal plans?
Since individualization is at the forefront of my core values, I do not include cookie cutter meal plans because I know for a fact they do not work for every petite. I am here to be your guide and give you a menu of options to choose from (that feel best for you) to help you create your best path to results.
I'm not petite but I'm a coach who works with petite women, will this course help me?
YAS! This course can definitely help you understand the struggles petite clients face and how you can take a modified approach without sacrificing her strength, hormones, or sanity. (P.S. You can even use this professional development as a write off!)
I already have a coach, personal trainer, nutritionist, etc. Can I take this course or should I wait?
Of course! In my humble opinion, you can never have too much information, knowledge, and support when it comes to your health and well-being. By taking the initiative to learn more about nutrition and fitness, you're not "cheating" on your current support system. On the contrary, you're demonstrating a proactive approach to your own growth and development. I believe your coach, trainer, or dietician will be proud to see your commitment to expanding your knowledge and taking control of your health journey. You can never have too many opportunities to learn, grow, and gain additional support. You're on an incredible path to becoming the best version of yourself, and this course can be a valuable asset alongside your existing guidance.
Up until now, there was no instruction manual for petites.

We've tried to hang with the taller gals only to end up feeling tired and frustrated.

So let me ask you this...

Wouldn't it feel nice to know--for certain--that all the time and energy you put into living a healthier lifestyle ACTUALLY aligns well with and feels good to YOU?

If the answer is a resounding "HECK YES!" Let's make it happen!
