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, keeping that waistline trim 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 trial and error

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:


It's time to quit the GUESSING GAMES & the CRASH DIETS because

Understanding Your Petite Body Just Got Easier.👏🏿 Than.👏🏻 Ever.👏🏽

Frequently Asked Questions

When does the course start and finish?
The course starts now and never ends! It is a completely self-paced online course - you decide when you start and when you finish. Some ambitious babes will finish this course in one night, others in one weekend, and some might want to take a small bite of the information at a time. If that's the case, I suggest completing one module per week so that you "graduate" 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 you like - across any and all devices you own. Since my work is research & evidence-based, you'll also get all (if any) updates I make to this course in the future.
Is this a weight loss program?
While I realize that most of you are interested in weight loss, the information provided in this course is NOT just for weight loss but for living a healthy lifestyle that feels good for and fits YOU. Whether your goal is weight loss, muscle gain, maintenance, or just more confidence in your healthy lifestyle, you'll gain a better understanding and connection to your petite needs. If you're goal is weight loss, the major break-through you’re about to experience will not only help you to shed some of the fluff so you can feel good in that crop top for once, but will help you to embrace every inch of your uniqueness and be even more proud to be petite!
Does this program include meal plans & workouts?
The Funsized Formula is not an exercise or diet program but rather an educational program. You won’t get exact meal plans or workouts but you’ll learn the foundational concepts which will enhance your understanding and connection with your petite body. We are literally going to re-wire to re-build your relationship with food & fitness because 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 and a sustainable healthy lifestyle. With that being said, you do have the option to receive training programs! One of the bonuses you'll receive after you enroll is a risk-free full month trial of The Funsized Fitness App consisting of petite-friendly workouts ($24.97 value)
What if I rather just have you coach me?
Let's see if we're a good fit! Go to to learn more about my 1:1 nutrition & fitness coaching for women under 5'3".
I'm not petite but I'm a coach who works with petite women, will this course help me?
ABSOLUTELY! I love that you want to be a better coach for your petite clients! This course will definitely help since you won't find this in-depth information in standard textbooks and other learning materials. (P.S. You can even use this professional development as a write off!)
I already have a coach, personal trainer, dietician, etc. Can I take this course or should I wait?
Of course! In my opinion, you can NEVER have too much information, knowledge, & support! And for the record, you won't be "cheating" on your coach/trainer/dietician for taking the initiate to learn more about nutrition & fitness. In fact, I think they'll be proud!
Up until now, there was no instruction manual for petites.

We tried to hang with the big gals only to end up feeling fatigued and defeated.

So let me ask you again...

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?
