What if your yoga practice is the reason you’re not getting stronger?
Sounds backwards, right? But here’s the thing, your body in your 40s has changed. Your practice hasn’t.
That’s why the flows you’ve been loyal to for years… suddenly don’t work the way they used to.
They feel nice in the moment, but you’re not seeing strength, tone, or stamina stick around.
Here’s the shift: You don’t need more yoga. You need the RIGHT kind of yoga.
👇 This is where your yoga practice finally clicks with your changing body.
Introducing....#fortify40 2.0
A 6-week strength-based yoga program for women in their 40s who want to build muscle, keep their strength, and feel supported as they age.
Yep. All with just 2 focused session per week.
Fortify40 2.0 isn’t about starting from scratch.
It’s about building on what’s working, and and finally seeing progress you can feel.
⚡️ Build muscle and strength - with progressive, strength-based yoga sequences that layer week by week
⚡️ Practice with intention - no more random YouTube flows that don’t add up to anything
⚡️ Improve stability, keep your joints happy, and maintain strong, capable muscle tissue as you move through midlife
This round is designed for women who already know yoga feels good… but are ready for a structure that actually works HARDER for them.
Less guessing. More clarity. And a plan that meets your midlife body exactly where it’s at - without burnout, overwhelm, or hustle.
Because building strength in your 40s isn’t about pushing harder.
It’s about practicing smarter.
{Need proof it works? The stories below show exactly what women 40+ have experience inside Fortify40 2.0.👇 💛}
Why Strength Hits Different After 40?
Here’s the thing… once you’re in your 40s, your body doesn’t play by the same rules anymore.
🙄 You probably already feel it: muscles that aren’t quite as firm, stiffness that takes longer to shake off, recovery that drags out a bit more than it used to.
🙄 And sometimes it feels like your mind is running circles around itself while your body’s quietly saying, “Hey, we need a new plan here.”
That’s not failure. That’s biology.
Women naturally lose about 3–5% of muscle per decade after 40 if we don’t do something about it.
And muscles? They’re not just about looking toned in a tank top {though, sure, that’s nice too}.
They’re about keeping your metabolism steady. Supporting your bones. Helping you recover faster, move with more ease, and feel capable in your own skin.
Bottom line?

Muscles matter, and it takes more than random flows to keep them strong.
What your body needs now isn’t endless workouts. It’s focused ones.
Yoga that challenges you to build and keep muscle, and proving that strength doesn’t have to come with burnout.
That’s why I built Fortify40 2.0.
Two sessions a week. Progressive. Intentional. Enough to create real change.
No grind. No guilt. Just a structure that pushes you where you need it, and shows you, week by week, that your body is still strong, capable, and changing for the better.
INTRODUCING…
#fortify40 2.0
A 6-week strength-based yoga program for women in their 40s who want to build muscle, keep their strength, and feel supported as they age.
The full course breakdown
-
![]()
Phase 1 - shoulders
Week 1-2
The first two weeks aren’t about going “all in.” They’re about giving your body the support it needs to handle what’s coming next.
We’ll start with your shoulders, because if they’re strong and steady, the rest of your practice feels smoother and more grounded.
Here’s what that looks like:
🛠️ Full-body flows that connect your shoulders, core, hips, and legs so everything’s working together instead of in isolation.
🛠️ Sequences that push you just enough to feel the effort, but still let you get up the next day without feeling wrecked.
🛠️ Movements that build real strength while keeping mobility in the mix, so you feel steady and powerful without losing ease.
And if you’re worried about “keeping up”, don’t. Every pose has variations and modifications. You’ll always have a way in, no matter your starting point.
By the end of this phase, you’ll feel the difference: more stable through your shoulders, clearer in your alignment, and more confident in how your body moves. That stability becomes the baseline for the deeper strength work ahead.

Phase 2 - core
Week 3-4
Now that your foundation is set, it’s time to shift the focus to your core, the powerhouse that supports every single movement you make, on and off the mat.
Here’s what that looks like:
🔥 Sequences built to wake up your deep core muscles, while also pulling in your hips, shoulders, and back, because your core doesn’t work in isolation.
🔥 Poses that challenge your stability and balance, helping you feel more supported in daily life {yes, even when hauling groceries or sitting at a desk all day}.
🔥 Alignment cues to make sure you’re strengthening safely, reducing risk of injury, and getting the most out of each movement.
Expect to meet more challenging variations during this phase, not to overwhelm you, but to layer strength progressively.
By the end of Week 4, you’ll notice your core feeling stronger, steadier, and more capable… a strength you’ll carry into every part of your practice {and your every day life}.

Phase 3 - hips & legs
Week 5-6
In the final stretch, we shift the focus to your hips and legs, the foundation of powerful, grounded movement. Strong lower body = better balance, more stability, and freedom to move with ease.
Here’s what that looks like:
⚡ Sequences designed to strengthen your hips and legs while also keeping mobility and flexibility in play.
⚡ Poses that activate multiple muscle groups at once, building power while lengthening and opening.
⚡ Progressive challenges that help you build endurance and discover just how capable your lower body really is.
By the end of this phase, you’ll feel the difference: muscles that engage deeply, joints that move more freely, and a sense of strength that carries into every step of your daily life.
This is where everything you’ve built in Weeks 1–4 comes together, leaving you stronger, steadier, and more confident in your body.

Hi, I'm your yoga teacherNatalia Rennie
the 47-year old creator of #fortify40 2.0 and founder of nataliarennie.com!
With 17 years of practice and 9 years as a professional yoga teacher, I’ve learned that real results come from a mix of consistency and smart intensity. That’s exactly what this program delivers.
I became a certified yoga teacher in 2016. At first, clients didn’t come easily. I focused on showing up, gaining hours, and sharpening my skills. Somewhere in that journey, I discovered my true passion: helping women feel stronger and more at home in their bodies.
Fast forward to today, I’ve taught more than 3,300 hours of classes and guided countless women in building strength, resilience, and confidence through yoga.
My promise to you? To help you create consistent habits that support your health, strengthen your body, and steady your mind, so you can move through midlife feeling capable, confident, and comfortable in your own skin.

How do I know if this program is for me?who is this for?
This program was created with you in mind if you’re…
A woman 40+
Navigating midlife shifts and ready to adapt your yoga + strength routine to match your body’s needs.
Feeling the impact of changing hormones and noticing your strength or muscle tone just isn’t what it used to be.
Not brand-new to yoga. You know the basics and want a program that takes you further.
Craving direction and consistency, but still need the freedom to practice on your own schedule.
Tired of random YouTube classes that feel good in the moment but don’t actually build lasting results.
Ready to commit to yourself, prioritize your health, and feel stronger in both body and mind.
Who is this not for?
This program isn’t for everyone, and that’s okay. It likely won’t be the right fit if:
You’re looking for quick fixes or instant results. This work is about steady, lasting change, not overnight transformation.
You’re not able {or willing} to carve out a couple of practices each week. Consistency matters more than perfection.
You’re closed off to trying new approaches. Progress requires a bit of curiosity and a willingness to experiment.
You know deep down you’re not ready to commit to yourself right now. This program only works if you show up for it.
You’re only interested in yoga for relaxation or stretching. Fortify40 2.0 is designed to build strength. The flows WILL challenge you.
You prefer live, in-person classes and don’t enjoy following along with guided online practices. This program is flexible and self-paced, but it is online.

FAQ
-
The difficulty level of these yoga classes depends on your current experience and yoga proficiency level.
Each session provides options to customize your practice to your comfort, recognizing that the right balance is crucial for progress.
Sometimes, less can truly be more when it comes to yoga.
-
Yes, this will be a common concern, and warranted. Consistency is key, and by making these yoga sequence on the short side (30-45 minutes) hopefully that provides a low barrier to entry.
But bottom line, a lot of women won't be able to commit to 2 days a week, and that is fine. You need to make it work for you and your unique schedule and priorities.
The program calendar lays out a 2 day/week suggested schedule BUT, I’d like to see you commit at least 1 day a week.
-
Starting Tuesday, September 24th, you'll begin receiving two pre-recorded yoga flows.

Each yoga flow comes with a written description.
The program provides a systematic approach with a laid-out schedule, making it easy for you to follow and know exactly what to do and when.
The goal is to see improvements in your physique and strength through consistency.
You’ll be able to track your progress in the app, which can be really motivating when you get that yoga flow streak!
-
This comes up frequently, and the closed group provides an excellent platform for addressing questions on form or modifications to ensure a safe and effective practice.
The yoga flows will include modifications or alternatives. However, sequences may not be best for you if you’re dealing with chronic pain and injuries, or you have extremely limited mobility, or you are a true beginner who has never practiced yoga before.
-
You'll want to go for a comfy, non-slip yoga mat for your practice.
It not only gives you a stable surface but also ensures you're safe during your yoga sessions.
Consider using yoga blocks to adjust postures and vary intensities when you practice.
Yoga belt/yoga strap may come handy for deeper stretches and added support when needed.
-
Pre-recorded sessions are sent out to your inbox every Tuesday for 6 weeks.
If your goal is to see improvements in your body, going for a systematic approach is the way to go.
While you might stumble upon random yoga classes on YouTube or squeeze in the occasional studio class (if time allows), it can work for a bit but might not be the most effective route for building strength, flexibility, and balance.
-
