How breathwork can improve your strength and mobility!

It is more than Inhale & Exhale!

Introduction: Breathing Is the Beginning

Breath is often taken for granted. It is automatic, ever-present, and so foundational that we often forget its power. In movement practices like Pilates, Barre, and even traditional strength training, breath is the unsung hero. Your life begins with your first breath and ends with your last—a bold statement, yes, but one that reminds us of the sheer importance of this biological rhythm. While some fitness classes may not dedicate lengthy segments to breathwork, it's always there: shaping, informing, and supporting every motion. And when done intentionally, breathwork becomes an engine for strength, mobility, and even internal organ health.

Let’s explore how breath can become your secret weapon.



1. Breathwork as a Tool for Strength

Let’s start with the basics. When you breathe deeply and intentionally, your diaphragm and core muscles work in tandem. In Pilates, we emphasize 360 breathing—breathing that draws air deep into the lungs, expanding the ribcage laterally and into the back body. This type of breathing recruits the transverse abdominis, pelvic floor, and obliques—the core of your core.

Engaging these muscles with breath builds inner strength, creating a more stable foundation for outer strength. For instance, in Barre classes, when you exhale during exertion (e.g., a lift, pulse, or plank), you access more power. Breath provides rhythm, which improves coordination, and breath drives engagement, which improves muscle recruitment.

Over time, practicing breath-coordinated movement helps:

  • Improve posture and spinal alignment
  • Prevent injury by supporting the low back
  • Enhance muscle activation and endurance



2. Breath and Mobility: Creating Space from the Inside Out

Breath isn’t just for strength; it’s a vehicle for mobility. Think of a deep breath as internal stretching. With each inhale, your ribcage expands, your spine subtly lifts, and space is created between joints and tissues. With each exhale, you have the chance to settle, deepen, and elongate.

Deep breathing enhances mobility by:

  • Relaxing overactive muscles
  • Improving circulation to tight tissues
  • Encouraging the nervous system to shift from “fight or flight” to “rest and digest”
  • Facilitating deeper stretching and safer range of motion

In practical terms, a student who breathes deeply during a seated forward fold will experience more release in the hamstrings and hips than someone holding their breath and muscling through. In spinal rotations, breath can act as a lever to help the thoracic spine rotate more smoothly.

Intentional breathing helps us soften into movement. It brings a sense of flow, grace, and release.



3. The Diaphragm-Liver Connection: Why Breathwork Supports Organ Health

Here’s where science and holistic wisdom intersect beautifully. The diaphragm, your primary breathing muscle, sits just above the liver. With each deep breath, especially when you use diaphragmatic breathing, your liver is gently massaged.

This rhythmic compression and decompression has real health benefits:

  • It supports liver detoxification and lymphatic drainage
  • It stimulates circulation through the portal vein
  • It helps reduce stagnation, which can happen when we’re sedentary or shallow-breathing

In Eastern medicine and somatic practices, the liver is associated with anger, frustration, and energy flow. Supporting the liver with breath can be both a physical and emotional release. The gentle massage of breath may not be as flashy as a detox juice cleanse, but it’s a sustainable, daily ritual that helps the body process and heal.

The best part? You don’t need to lie down in meditation or chant to experience these benefits. Simply incorporating deep, diaphragmatic breaths into your Pilates mat practice, your morning stretch, or your walk around the block can make a meaningful difference.



4. My First Lesson in Diaphragmatic Breathing

When I was younger, I took singing lessons with a teacher who had a beautifully simple way of teaching us how to breathe from the diaphragm. She’d lay us down on the floor and place a giant book—a phone book, encyclopedia, or dictionary—on our bellies. Our job? Breathe in deeply enough to lift the book, then control the exhale slowly enough to let it gently fall.

At the time, it felt like a quirky exercise, but it planted the seed of breath awareness early on. It was my first tactile experience of diaphragmatic breathing, and I’ve never forgotten it. That moment taught me how breath could be physical, visible, and powerful—something that continues to influence my movement and teaching today.



5. Breath as the Teacher: Awareness, Control, and Healing

Your breath is your first feedback tool. If you’re holding your breath during a challenging movement, it’s a sign to check in: Are you over-recruiting certain muscles? Are you moving too fast? Are you pushing through pain?

Breath reveals our unconscious patterns. For many people, shallow chest breathing is a default mode—a result of stress, poor posture, or trauma. Teaching clients (and ourselves) to breathe more fully is not just a fitness goal but a health intervention.

Tools to retrain breath:

  • Try a breath-focused warm-up in Pilates: lying supine with knees bent, hands on the ribs, practicing lateral expansion.
  • Cue breath in every major movement: Inhale to prepare, exhale to engage.
  • Use tactile props: A small ball or yoga block between the thighs while curling up can help connect breath with deep core engagement.

As teachers and movers, we can use breath to:

  • Cue better alignment
  • Slow down rushed or sloppy movement
  • Offer clients a moment of rest or reset
  • Empower people to connect with their own bodies in deeper ways



6. A Final, Controversial Thought: The Marker of Life

It might sound dramatic, but it’s true: Your life begins with a breath and ends with one. In between, how many breaths do you take without noticing?

Even in classes where breath isn’t the focal point, it’s still the undercurrent. It dictates the tempo, shapes the energy of the room, and defines your ability to be present. When you start to work with your breath rather than around it, everything changes. You gain clarity, connection, and a sense of power from within.

Whether you’re cueing dozens of clients in a Barre class, guiding one-on-one Pilates sessions, or simply showing up on your mat, breath is your anchor. It is not just the thing that keeps you alive. It’s the thing that can make you feel more alive.



Conclusion: Breathe to Move, Move to Breathe

So the next time you're teaching or training, remember this: Breath is not an afterthought. It is a primary driver of strength, mobility, and vitality. It supports your liver. It engages your core. It creates calm. It fuels presence.

Integrating breathwork into your practice isn't about adding complexity. It's about uncovering what's already there. A quiet, steady rhythm that supports your best movement, your deepest healing, and your most grounded self.

So inhale with intention. Exhale with power. And keep moving—one breath at a time.

Why You Should Stop in Barre & Pilates
By Leslie Guerin April 8, 2025
“Barre Hurts My Knees!” — Or Does It? I hear this often. “I love Barre… but it hurts my knees.” Or: “My doctor said Barre isn’t great for joints.” And while I understand the concern, I also know this: it's not the Barre that’s hurting knees—it's how it's being done. Let’s clear something up right away: your knees are joints, not muscles. Their job is to connect and bend, not stabilize or initiate. When knee pain shows up in class, it’s rarely because of the movement itself—it’s almost always a red flag that the alignment is off, the muscles aren’t engaged the right way, or we’ve stopped listening to the body’s subtle cues. Barre (and BarSculpt especially) is not meant to hurt you—it’s meant to help you . Let’s dig into what’s really happening. Are We Listening to Our Knees? Your body is always talking to you. Sometimes it whispers. Sometimes it yells. In most cases, knee pain during or after Barre class is your body’s way of waving a little red flag, saying: “Hey! You’re leaning on me too much—I’m a joint, not a stabilizer!” We’re often taught to ignore those whispers. Push through. Work harder. No pain, no gain. But that mindset doesn’t belong in a BarSculpt class. We want you to listen. To get curious. To respond before things escalate. The Knee: What It Is and What It Isn’t The knee performs as a hinge joint. That means it’s designed best to bend and straighten. Not rotate. Not twist. Not stabilize your whole body. It connects the femur (thigh bone) to the tibia (shin bone), and it relies on the support of your muscles —especially your glutes, hamstrings, quads, and calves—to function well. When those muscles aren't firing correctly—either because of faulty alignment, poor cueing, or ingrained movement patterns—the knee joint ends up taking on more than it should. And that’s when the whispers turn to yells. Common Barre Mistakes That Can Aggravate the Knees Here are the three most common issues I see when people experience knee discomfort in a Barre (or sometimes even Pilates) setting: 1. Tucking the Pelvis During the Warm-Up This one drives me a little bananas. The cue to “tuck” the pelvis is still floating around out there like it’s 1999. Tucking under may feel like you're engaging your abs, but what you're really doing is: Shifting your pelvis into a posterior tilt Over-recruiting your quads and hip flexors Disconnecting from your glutes Removing natural shock absorption from your spine When you tuck your pelvis during thigh work, warm-up, or even standing work, you're sending that misalignment straight down the chain, overloading your knees. BarSculpt doesn't teach the tuck. We teach alignment. We teach engagement from the back body, so your front body doesn’t have to hold on for dear life. It’s safer, stronger, and more sustainable. 2. Misaligned Thigh Work Thigh work is meant to light up your quads, glutes, inner thighs—and yes, your core. But too often I see: Feet too wide Knees collapsing inward or pushing too far forward Torso leaning back or forward Weight shifting into the knees instead of staying in the heels and glutes This isn't just less effective—it's risky. Misaligned thigh work turns a strengthening exercise into a strain on your knees. In BarSculpt, we teach neutral pelvis , stacked joints , and abdominal engagement . We work with the natural mechanics of the body, not against them. 3. Using Joints Instead of Muscles It’s easy to mistake movement for effectiveness. Sure, you can dip a little lower. Sink into that plié. But if you’re using your joints to hold that position instead of activating your muscles—you’re just hanging on your knees. Muscles should be working the hardest in every position. That’s where strength comes from. That’s where change happens. If you’re ever in a pose and wondering, “Where should I feel this?” the answer should never be your knees. What to Do When Your Knees Start to “Talk” If your knees start whispering during class, here’s what I want you to do: Back off. You’re allowed to scale back. Check your form. Are your feet aligned? Are your knees tracking over your toes? Recruit your abdominals. Reconnect to your core—especially in thigh work. Reset your spine. Untuck that pelvis. Breathe. Find neutral. Ask questions. Your teacher (hopefully) knows modifications and better alignment cues. BarSculpt teachers certainly do. And above all, don’t push through the pain . That mindset doesn’t make you stronger—it just teaches your body to ignore its signals. Let’s Talk About Why BarSculpt Is Different I’m not here to knock other methods, but I will speak clearly about BarSculpt because I built it with longevity in mind. BarSculpt classes are: ✅ Alignment-focused ✅ Rooted in Pilates and functional movement ✅ Designed to challenge the muscles , not the joints ✅ Educator-led, not performance-driven We don’t want you to “look” a certain way in class—we want you to feel deeply connected, strong, safe, and energized. Barre Should Help You Move Better, Not Hurt Our bodies are designed to move. Movement is not the enemy—misalignment is. Barre (done right) improves posture, stabilizes the pelvis, strengthens muscles around the joints, and supports everyday life. BarSculpt is designed not only to strengthen but to educate. You learn how to move smarter—not harder—so your knees (and hips, and spine) thank you later. Final Thoughts: From Whispers to Wisdom When our knees talk to us, it’s tempting to push through. But ignoring those signals rarely ends well. Instead, we need to get curious. Is this a form issue? Am I tucking when I don’t need to? Are my abdominals doing their job? Is my teacher giving me cues that prioritize aesthetics over mechanics? When we shift the mindset from “more is more” to “aligned is more,” everything changes. Your workouts feel better. You feel stronger. You stop avoiding class and start looking forward to it. So no, Barre isn’t bad for your knees. Bad movement patterns are bad for your knees. Let’s stop blaming the method and start upgrading the message. Want to Learn More?
