fortify40 1.0
Build Core Strength, Improve Balance, and Strengthen Your Midsection in Just 4 Weeks.
A progressive, strength-based yoga program for women in their 40s who want results they can feel in less time per day then most spend scrolling for âinspoâ on Instagram.
THIS IS FOR YOU IF THAT SOUNDS FAMILIARâĻ
âĸ You feel less stable during basic movements â lunges, single-leg work, getting up off the floor
âĸ Small aches and tweaks show up more often
âĸ Your waistline feels softer and your clothes fit tighter
âĸ Your midsection doesnât feel as firm or supported
âĸ Your balance isnât as steady as it used to be
âĸ Your lower back gets fatigued more easily
Introducing....Everywhere you look, youâre being told {and seeing the evidence} that yoga should help, and yetâĻ
đŗ Youâve searched YouTube for âyoga for low back painâ more times than you can countâĻ
đŗ Youâve tried a few 30-day challenges promising strength, tone, or a âresetââĻ
đŗ Youâve signed up for classes or programs that sounded great in theory, until schedules, traffic, and real life made them hard to keep up withâĻ
You end up doing a little of everythingâĻ without feeling sure about any of it.
Yoga and strength are usually treated like two different things.
â One feels like too much.
â The other feels like not enough.
And when your energy goes up and down and your body doesnât feel the way it used to, itâs easy to hesitateâĻ
Even though you know you want to get stronger.
So instead of feeling stronger, more stable, and at ease in your bodyâĻ
youâre stuck between doing too much, not enough, or not knowing what to trust.
Itâs not that you donât want to get stronger. Itâs that youâre tired of doing things that take a lot of effort and donât really help.
-
Trying video after video on YouTube to âfix your core,â but your back still does most of the work.
-
Going to classes that promise stronger abs, then leaving unsure if you actually got stronger or just sore.
-
Doing every plank and core challenge you see online, even though it mostly ends up hurting your lower back.
-
Stretching a lot to feel looser, but sitting down later and feeling just as tight in your hips and back.
-
Mixing bits of advice from physio videos, workouts, and programs because you know your core matters, but nothing really sticks.
-
Trying exercises like bridges or bird dogs and wondering why they still feel awkward or confusing without someone clearly showing you how theyâre supposed to work.
Strength training is often treated as the only *real* way to get stronger.
But itâs not the only way to build core strength.
And for many women in midlife, itâs too much to start with.
Hereâs the good newsâĻ
You donât have to choose between doing nothing and throwing yourself into workouts that leave you wiped out, sore, or second-guessing your body.
There IS a way to build core strength thatâs easier on your joints and fits your energy right now.
âĻand it meets you where you are right now.
I know this because Iâve spent years teaching women in their 40s how to get stronger with yoga thatâs easy to follow, slow enough to keep up with, and built for changing bodies.
IF youâreâĻ
đĢŖ Tired of advice that ignores recovery, joints, and hormonesâĻ
đĢŖ Wondering if harder and heavier still make senseâĻ
đĢŖ Looking for a way to build core strength that actually feels doableâĻ
THIS is for YOU.

introducing....FORTIFY 40 1.0
Strength-based yoga for women in their 40s focused on core strength, back support, and stability.
⨠I love your classes and the way you teach and explain. It has the right level of difficulty that challenges me and makes me improve every time I do a yoga session with you.
You may have tried to push your way into feeling stronger. Jumping into tougher classes. Faster yoga flows. Things that used to workâĻ or looked like they should.
But your bodyâs in a different place now. And forcing it usually just leads to soreness, frustration, or that quiet thought of, maybe this isnât for me anymore.
Fortify40 1.0 was built to slow things down. Not to make it easierâĻ but to make it make sense.
This is strength you build gradually. Step by step. In a way your core, joints, energy, and recovery can actually keep up with.
No pushing through. No guessing. Just a steady way to get stronger that fits your life right now.

Hereâs how weâll make it happenâĻ
Fast, intense workouts are tempting because they feel like a shortcut. Push harder and everything will click.
But when your bodyâs changing, that approach usually backfires. More soreness. Slower recovery. And not much to show for it.
Fortify40 1.0 takes a different approach.
Over four weeks, you follow strength-based yoga thatâs taught slowly and on purpose, so your body can actually adapt.
Each week focuses on a specific area: abdomen, side body, back and glutes, and pelvic floor.
Classes are 30â45 minutes, done twice a week. Enough to build strength, without draining your energy.
You move at your own pace. Pause, repeat, or keep it lighter when you need to.
And instead of starting over every time life gets in the way,
you follow a clear progression that builds strength you can actually feel, week by week.
Hi đ Iâm Natalia. And itâs fair to askâĻ who am I to guide you through this?
Iâve spent the last 18+ years teaching yoga, with a big focus on women who want to feel strong, steady, and confident in their bodies again.
Not perform-y strong.
Not âpush through itâ strong.
Real, everyday strength that actually supports your life.
Over the years, Iâve taught thousands of hours of classes and worked with women navigating joint pain, hormonal shifts, injuries, and that frustrating feeling of, my body doesnât respond the way it used to.
What Iâve learned is this:
Yoga works.
Strength works.
But in midlife, they need to be approached with more intention and a lot less pressure.
Thatâs what Fortify40 1.0 is built on.
Itâs not about chasing harder poses or pretending your body hasnât changed.
Itâs about using yoga as a clear, structured way to build strength you can trust.
If youâre here, Iâm guessing youâre not looking for extremes.
Youâre looking for something that feels thoughtful, supportive, and doable.
Thatâs exactly why this program exists.
Fortify40 1.0This program trains your core the way your body actually uses it.
On the floor. On your hands. Standing. Balancing. Moving slowly enough that the right muscles can actually turn on
Youâll work your abs, yes! But also your back, glutes, hips and pelvic floor. The way they need to support you when you sit, stand, bend, twist, walk or carry things through your day.
The difference is finishing a workout feeling soreâĻ.
âĻOR moving through the rest of your day feeling more supported.
The C.O.R.E. Method & The structure behind Fortify40 1.0
Before we go any further, this matters. đđ
If yoga hasnât stuck for you, itâs probably not a motivation problem. Itâs a design problem.
Most approaches donât account for midlife bodies, real schedules, or fluctuating energy. And no amount of âpushing throughâ solves that.
Fortify40 1.0 is built on a framework Iâve refined over years of practice and teaching, by watching what actually keeps women engaged and getting results.
Itâs not about doing more. Itâs about doing what works.
-
C â Consistency
Not #yogaeverydamnday. Just regularly.
You donât need perfect weeks or endless motivation. You need something you can keep doing, even when life gets busy and youâre tired.
Fortify40 1.0 is built around a realistic schedule so practice becomes something you return to, not something you fall off and beat yourself up about.
Consistency is how strength builds. Period.
-
O â Order
Structure matters more than intensity.
Classes arenât random. Youâre not winging it based on how you feel that day.
Each session has a plan. Each week focuses on one thing. Your body knows what itâs working on, why itâs working on it, and how it all fits together.
Less confusion. Less overload. More progress.
-
R â Repetition
Because thatâs how bodies learn.
If youâre always doing something new, your body never gets a chance to adapt.
Fortify40 1.0 gives you time to repeat movements, revisit patterns, and actually feel improvement, instead of wondering why nothing sticks.
Repetition isnât boring. Itâs how strength shows up where you need it.
-
E â Engagement
Pay attention. Thatâs the work.
You donât need to push harder.
You need to stay present.Notice whatâs working, and adjust when it doesnât.
Thatâs how yoga becomes useful, not just something you âdid.â

Got questions?
-
No.
And itâs also not âpush through it and hope for the bestâ yoga.Fortify40 1.0 is structured, strength-based yoga.
Taught slowly enough that your body actually learns what itâs doing, instead of guessing and compensating.
Thatâs the difference.
Because letâs be honestâĻ
A lot of yoga lands in one of two places:Nice, but not effective.
Or intense, but not supportive.
This lives in the middle, where strength actually sticks.
Not because you pushed harder.
But because the work made sense. -
Because most yoga classes are designed to be interesting, not effective.
They change constantly.
They move quickly.
They assume your body will justâĻ figure it out.
And for some bodies, maybe that works.
But if youâre in your 40s and beyond, that guessing game usually shows up as sore backs, tight hips, or feeling like the work keeps landing in the wrong places.
Fortify40 1.0 is different, because itâs structured.
You know:
WHAT youâre working on.
WHY youâre working on it
and HOW it connects to the rest of your body.
Nothing is random. Nothing is rushed.
Thatâs why people stay.
Thatâs why my students come back again and again.Not because itâs entertaining.
Because it works. -
I donât wing it. đ¤ˇââī¸
- > Iâm not improvising.
- > Iâm not throwing sequences together and hoping your body catches on.Fortify40 1.0 is taught with structure.
With intention. With progression you can actually feel.So youâre not guessing what should be working.
Or wondering if youâre âdoing it right.â
Or leaving class thinking, wellâĻ I moved, I guess?Iâve taught this way for years, and Iâve watched bodies change when the work makes sense.
And thatâs why over 90% of my students come back.
Not because itâs flashy, or trendy. But because they trust the process.
And once you feel that difference?
You donât really want to go back. -
If your workouts are translating into feeling supported, strong, and stable in daily life, maybe not.
But IF you:
Still feel it in your lower back
Still feel disconnected from your core
Still feel like your strength doesnât show up when you need it
This fills the gap most workouts miss.
-
Often sooner than you expect, but probably not in the way youâre used to measuring progress.
For many women, the first thing they notice isnât strength or flexibility.
Itâs relief.⥠Relief from feeling unsure about what theyâre doing.
⥠Relief from that low-level tension of trying to âget it right.â
⥠Relief from the sense that their body is unpredictable.You might notice that:
getting up from the floor feels less effortful
transitions feel less awkward or hesitant
youâre not bracing or holding your breath as much
movements feel more familiar instead of foreign
Those are early signs your body is learning, not just exercising.
Visible strength takes time. Thatâs normal.
But when the work is structured, the nervous system settles firstâĻ and everything builds from there.
Thatâs usually when women think, âOkay. This feels different.â
And thatâs when consistency gets easier.
-
Perfect. Youâre in the right place.
Flexibility isnât the starting point here.
Awareness is.
Most people donât need to stretch more, they need to learn how to use their body better.
Thatâs what weâre doing.
-
Short answer? No! This isnât designed to make your back or hips work harder than they already are.
The whole point of this series is to stop your back and hips from compensating.
Thatâs why movements are taught with:
options
pauses
and cues that respect joints and recovery
Translation: thereâs room to adjust. Always.
Youâre never asked to override your body just to âkeep up.â
Thatâs not the job here.Each class includes built-in modifications, so youâre not stuck forcing shapes or guessing what to do if something doesnât feel right.
And if you want a second set of eyes? Thatâs what the private group is for.
You can ask questions, check alignment, or get support when something feels off, so youâre not left wondering if youâre doing it âwrong.â
HoweverâĻ.
If youâre dealing with chronic pain or a more serious injury, this might not be the right entry point, and thatâs not a failure. Thatâs good judgment.
In that case, itâs always best to check in with your doctor or physio first.
Your safety comes first. Always.
This series is here to support your body, not test it.
-
Yes, and thatâs intentional.
Fortify40 1.0 avoids the constant intensity and randomness that can be harder to recover from in midlife.
Instead, we focus on:
Consistency
Manageable effort
And giving your nervous system time to adapt
You build strength without burning yourself out.
-
Youâll have access to a private space with other women in the program â a place to ask questions, compare notes, and stay connected as you move through the work.
Youâll also have direct access to me throughout the program via the platform.
đ If something doesnât make sense, you can ask.
đ If you need clarification, youâll get it.
And when needed, I can create short demonstration videos to show things visually, so youâre not stuck translating cues on your own.
This isnât hands-off.
And youâre not left guessing. -
You get immediate access to all 8 classes â a 4-week program with two sessions per week.
Nothing is locked.
Nothing is dripped.You start when youâre ready, and you move at your own pace.
From there, I check in once a week â to keep you focused, grounded, and actually doing the work.
Not to chase you.
Not to motivate you.
To keep you on point.The structure is already there.
Each class fits into a clear progression.
You know what youâre working on.
You know why it matters.
And you can repeat what helps â without starting over.Every session comes with a short written guide.
Because clarity beats surprises.And yes, you can track your progress in the Stan Store app.
Not because you need accountability gimmicks.
But because following through feels good. -
You donât need much to get started.
Just a few basics that help the practice feel more supported.A non-slip yoga mat â something stable enough that youâre not worrying about sliding.
A pair of yoga blocks â useful for adjusting poses, supporting balance, and making positions more accessible.
A strap (or a belt or towel) â helpful when range of motion isnât there yet.
None of these are required on day one. But they do make the work feel better in your body.
Use what you have.
Add tools as you go. -
If youâre already thinking,
âOkayâĻ but what happens when I miss a few days?âGood. That tells me youâre paying attention.
Because this isnât built on motivation.
Itâs built on returning.⨠No streaks to protect.
⨠No falling behind.
⨠No imaginary finish line you somehow missed while living your life.You stop.
You start again.
Right where you left off.âCause strength doesnât come from pressure. It comes from repetition you can actually live with.
And letâs be honest, life doesnât ask for permission.
Work gets busy.
Kids get sick.
Energy dips.
You blinkâĻ and the week is gone.Which is exactly why these classes are pre-recorded.
You practice when it works. Morning. Evening. Between meetings.
All of it counts.
Each class runs 30â45 minutes.
And if some weeks you only get one in?Still counts. Still works. Still part of the process.
This isnât about being perfect.
Itâs about being available to come back.Start where you are.
Return when you can.
Let the strength build quietly, without drama.đ -
You get 7 days to try the program.
^^^ I want you to decide based on experience, not hope, pressure, or a sales page.
If you try the classes and itâs not the right fit, you can request a full refund within the first 7 days. Just send a message.
If you choose to opt out, your access to the program and member space will end at that point.
After the first 7 days, refunds arenât available.
So donât sit on it.
Log in.
Do the classes.
See how it feels in your body.Then decide.

AND IF YOU'RE WONDERING IF THIS IS RIGHT FOR YOUR STAGE, RIGHT NOW?
âī¸ How many of these do you tick off? âī¸
who is this for?
â You want to build strength without pushing your body into exhaustion, pain, or recovery spirals.
â Youâre in your 40s (or beyond) and know your body needs more support, not more intensity.
â Youâre new to yoga or coming back after a break, and want clear guidance instead of guessing your way through classes.
â Youâre tired of workouts that feel random, rushed, or disconnected from how your body actually works right now.
â You want to feel stronger for real lifeâĻ stairs, carrying things, moving with more easeâĻ not just checking a workout box.
â Youâre ready for a steady, structured approach that builds strength over time, without needing to âgo hardâ to make progress.
Who is this not for?
â Youâre looking for a quick fix, a 7-day reset, or something that promises instant results without consistency. This is steady strength, not magic.
â You love high-intensity workouts, pushing through soreness, and chasing the burn at all costs. If thatâs working for you and your body feels great, keep going.
â You want to rush through poses, skip foundations, or treat yoga like a box to check. Fortify40 1.0 is slower on purpose.
â Youâre not willing to repeat movements or stick with a plan long enough for your body to actually adapt. Strength takes time. Thereâs no way around that.
â Youâre hoping someone else can âdo the work for you.â This program guides you, supports you, and shows you howâĻ but you still have to show up.
