WORDS FROM

OUR WOMEN.

" This gym is truly amazing! You become part of a beautiful community where strong and fierce women uplift each other, celebrating every accomplishment together. "

- ALMARLY

" I’ve discovered how strong I really am and it’s because of these ladies, pushing me to succeeded. They play great music and even give you some karaoke while you’re lifting heavy ass weights.(lol) "

- MIRACLES

" This is a safe space where women are working on their fitness side by side. I've done both group sessions and going on my own. I also love using the sauna. It's always clean and a pleasant workout experience with all the machines you need. I'm so grateful Fierce is a part of my life! "

- PREET

" After a bike accident that left me with an injured elbow and shoulder, I completely lost the confidence to return to a traditional gym setting on my own. That all changed when I joined this all-women’s gym. "

Take a little look inside the Fierce Lioness app 🔥

From structured training programs and exercise demos to logging your weights, tracking your progress and viewing your workout history, it’s all right at your fingertips.

And the best part? It’s FREE with your Fierce Lioness subscription.

No separate subscription. No ads.

📲 Download the app and let’s get to work! Dm us to get started

INTRODUCING THE FIERCE LIONESS FITNESS APP 💖

We created this for the woman who wants to feel stronger, more confident and more at home in her body.

The woman who is balancing work, family, relationships, responsibilities and everything else life throws her way while still trying to make time for herself.

Because we know how easy it can be to put yourself last and we want to help make choosing yourself a little easier.

For the first time ever, you don’t have to be a member of our gym to train with us. Now you can bring the Fierce experience with you. Whether you’re training at your local gym, traveling or wherever life takes you.

Inside the app, you’ll have access to:
✨Fierce workout programs
✨Exercise demonstration videos
✨Everything you need to track your weights, see your progress and continue getting stronger

We wanted to make quality training more accessible and as affordable as possible for women who are ready to see how strong they truly are.

You may not be able to walk through our doors but now Fierce can come to you.

Ready to become part of the Fierce community? Send us a message to get started! This is only the beginning 💖

Once you start paying attention to labels, you can’t unsee them.

So many everyday products are filled with long ingredient lists, additives, gums, preservatives and artificial dyes.

If you’ve ever dealt with bloating, digestive discomfort or just constantly feeling “off” it might be worth taking a closer look at what you’re eating. Sometimes the biggest changes come from simply becoming more aware of what’s in your food.

Who wants to see more Claudia approved items?

Honestly? It’s not luck.
It’s a choice.

There are mornings I don’t feel like getting up. There are days when working out is the last thing I want to do. But I know how much better I feel when I move my body, get stronger and do something for myself.

So I make the time.
I prioritize it.
I show up even when I don’t feel like it.

Because nobody accidentally ends up where they want to be.

Feeling good looks a little different when you’re this strong 🔥 #fiercebabes #strongisbeautiful #womenwholift #strongwomen

Scientists said the bob improves form. Who are we to argue?

At some point you stop asking, “What can I eat to get fit?” and start asking, “What can I do to feel my best?”

It’s not about dieting forever. It’s about building habits you genuinely enjoy, finding foods that fuel you and creating a lifestyle you don’t constantly need a break from.

That’s when it becomes sustainable ♥️

If you want your step ups to grow your glutes:
- Slight forward lean
- Sit back into your glutes
- Create tension
- Control the way down
- No push off

Feel the stretch. Move with intention.
That’s the difference.

In August 2020, Claudia took a leap of faith and opened Fierce Lioness Fitness on her own.

In November 2020, Massiel walked through the doors of Fierce as a member.

What started as a coach and member relationship quickly turned into a friendship. As Fierce grew, Claudia asked Massiel more than once to become a trainer, but the answer was no, twice.

In September 2022, Massiel joined the Fierce coaching team. Three years later, the partnership that had already been built, became official.

The truth is, partnerships aren’t built the day two people decide to work together, they’re built in the years before. Through trust, shared values, hard conversations and choosing each other over and over again.

A lot of people spend years searching for the right business partner. We never went looking for one. We found one.

And because that foundation came first, every woman who walks through our doors gets the best of both of us ❤️

Learning how to engage your core is one of the most important skills you can develop in the gym. It helps protect your back, creates a more stable foundation and allows you to generate more force during your lifts. A stronger core doesn’t just mean stronger abs, it means stronger everything.

Most people think a strong core means having abs.

It doesn’t.

Your core is responsible for creating stability, protecting your spine, transferring force, and helping every lift feel stronger and more controlled.

If you’ve ever felt unstable during lifts, your lower back takes over or you’ve hit a plateau, the problem might be the smaller stabilizing muscles that aren’t doing their job.

That’s why we don’t just focus on lifting heavier at Fierce. We focus on teaching your body how to move well, create force and control it.

Strength isn’t just about how much weight you can move. It’s about how well you can control it.
——

#coretraining #strengthtraining #womensfitness #functionalstrength #gymtips

More weight doesn’t always mean more progress‼️

Increasing your range of motion can create a greater stretch on the muscle and make the movement more effective. But that doesn’t mean forcing yourself deeper just for the sake of depth. Your range of motion should only go as far as you can control it with good form.

Before you add more weight ask yourself:
Can I control the full rep?
Can I create more tension?
Can I improve my range of motion?

Progressive overload isn’t just about lifting heavier. Better reps are progress too 🤞🏽

We need to start talking about what trainers go through 🥹

Stop overthinking it. Stop chasing every social media trend and just move

Six years ago, Fierce Lioness Fitness was just a dream inside a garage.

Today, it’s a home for hundreds of women who have trusted us with their strength and some of the biggest chapters of their lives.

Every milestone, every early morning, every late night, every challenge, every laugh, every PR, every class, every hug… it all led us here. And none of it would have been possible without the incredible community that chose to believe in us.

To every woman who has ever walked through our doors, thank you for trusting us💗

To every trainer who has poured their heart into coaching, thank you💗

To our founder, Claudia, for having the dream that started it all💗

To everyone who has ever recommended Fierce, shared a post, brought a friend, spoken our name with love or cheered us on from afar, thank you!!! You have all played a part in keeping Fierce alive and helping it grow into what it is today.

And while we’ve grown so much over the last six years, the mission has never changed: to create a place where women feel strong, supported and capable of more than they ever imagined.

Here’s to six incredible years… and to many, many more.

Happy Anniversary, Fierce Lioness Fitness 💗🥹

Today’s challenge: Can you broad jump your height? 🤔
Watch to see who made it... and who definitely didn’t LOL

Now we challenge YOU! Try it, tag us and let us know if you passed

Fierce babes get ready these are in this month’s program 😎

#fitnesschallenge #jumpchallenge #explorepage

The first pull-up feels impossible. Then, one becomes two. Two becomes four ♥️

More than a gym. A space built for women 💗 Come see what makes Fierce different

Most women don’t need another workout plan, they need someone to guide them through it.

A strength coach does more than count reps. We meet you where you are, create a plan that fits your goals, teach you how to train effectively and keep you consistent long enough to see real results.

Building muscle isn’t about doing more.
It’s about doing the right things, consistently.

If you’ve been feeling stuck, maybe it’s not a lack of motivation. Maybe it’s a lack of guidance.

💗 Send this to a friend who’s ready to start lifting with confidence

🍑 Peach Perfect Pilates
On the Mat x FIERCE

Safe to say… we all left a little peachier than we arrived 😅

What a night! We laughed, we shook and we sweated in places we didn’t even know could sweat

A huge thank you to everyone who joined us and to @roselisfit @roselisfitfuelbar for treating everyone to wellness shots after class! ♥️

This collab everything we hoped it would be. Thank you Michelle for an amazing class 🫶

Should we do another On the Mat x Fierce event? Let us know in the comments!👇
