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.

From Springs to Confidence

Let’s be honest: we’ve all done it at some point. You’re rushing from home, work, or errands, and you head to a Pilates class without giving much thought to what you’re wearing underneath your workout clothes. You throw on leggings, a top, and—without hesitation—your regular bra. After all, it’s just Pilates mat. It’s not running or jumping. How much could it really matter? The answer: a lot. In fact, wearing a traditional bra to Pilates mat class is one of the most common and avoidable mistakes I see women make. It’s not just about fashion—it’s about biomechanics, spinal comfort, and setting yourself up for the best experience possible. What you wear directly affects how your body feels and functions in class. And while Pilates is all about building strength, mobility, and alignment, the wrong gear—especially the wrong bra—can sabotage your comfort, compromise your performance, and even contribute to back pain. Why the Regular Bra Doesn’t Work for Pilates A traditional bra is designed with one goal: to shape and support breasts under everyday clothing. Most are structured with: Rigid underwires that press against the ribcage. Narrow straps that dig into the shoulders. Hook closures that create pressure points along the spine. Materials meant for aesthetics, not breathability or movement. That’s fine when you’re sitting at a desk or going out for dinner. But once you lie down on a Pilates mat and start rolling, curling, flexing, and twisting, all of those design features work against you. Here’s why: Spinal Discomfort – Pilates mat work involves a lot of supine (lying on your back) positions. The hook-and-eye closure digs into your spine, making it impossible to fully relax into the mat. That constant pressure leads to tension and pain. Restricted Movement – Underwires and rigid fabrics restrict natural rib expansion. Pilates breathing is three-dimensional—it requires your ribs to expand outward and back into the mat. A stiff bra limits this, creating shallow breath and less effective core engagement. Strap Pressure – Narrow straps dig into your shoulders during roll-ups, teasers, or any exercise where arms are overhead. Over time, this creates tension in your neck and upper back, distracting you from the precision Pilates demands. Compromised Flow – Pilates is about finding flow and ease. If you’re constantly adjusting straps or wincing at a clasp digging into your back, you’re not flowing—you’re fidgeting. The Importance of Costume Choices in Pilates Joseph Pilates himself often referred to “contrology” as an art form, not just an exercise method. He cared about alignment, grace, and the whole-body experience. What you wear is part of that experience. Think of it as your “costume” for the role you’re playing in class: a student committed to moving with control, precision, and awareness. If your outfit is working against you—pinching, digging, or restricting—you’re not able to embody the method fully. When we talk about costume choices, we’re not talking about fashion statements or brand labels. We’re talking about gear that supports your physical comfort, safety, and performance . What to Wear Instead The good news? There are better options—gear that is designed for movement, breath, and spinal health. Sports Bras with Wide Bands Choose bras without clasps or underwires. Wide, flat bands distribute pressure evenly so there’s no digging when you lie on your back. Look for materials that are stretchy but supportive, allowing ribcage expansion. Straps that Support, Not Dig Racerback or cross-back straps often provide better distribution and freedom of movement. Adjustable but wide straps help customize fit without cutting into your shoulders. Seamless Designs A seamless sports bra reduces irritation from seams or hardware. The smooth surface also means less distraction when rolling or twisting. Breathable Fabrics Moisture-wicking fabrics keep you comfortable, especially in longer classes or when working deeply into your core. Breathability supports better skin comfort and prevents overheating. How the Right Gear Elevates Performance Some may wonder: “Isn’t Pilates gentle enough that it doesn’t matter?” Actually, it’s precisely because Pilates is subtle, precise, and deeply connected to body awareness that gear matters even more. When you’re wearing the right bra and clothing: You breathe better. Your ribs can expand, making core activation more effective. You move better. Nothing digs, pulls, or distracts you. You focus better. Your mind stays on alignment, not discomfort. You recover better. Less unnecessary tension means less strain post-class. Pilates is about efficiency. Every detail—your posture, your focus, your gear—affects how efficient your practice is. The Back Connection Why do I emphasize the back specifically? Because back pain is one of the most common reasons clients come to Pilates. When you wear a traditional bra in class, the hooks and underwires don’t just cause temporary discomfort—they can exacerbate chronic back tension. Imagine lying on a hard clasp for a 50-minute class: your muscles subtly guard and tighten around that pressure the entire time. That’s the opposite of what Pilates is meant to achieve. Pilates builds a strong, supported back by improving spinal mobility, core stability, and posture. Don’t undermine that by placing an uncomfortable piece of hardware directly under your spine. A Personal Note as a Teacher As someone who has been teaching Pilates and Barre for over 26 years, I’ve seen every wardrobe choice imaginable. I’ve seen clients show up in jeans, in slippery socks, in bras with enough underwire to set off airport security. And every single time, their experience was compromised—not because they lacked strength or effort, but because their clothing was working against them. When I suggest a gear change, it’s never about judgment. It’s about giving clients the best chance to feel what Pilates really offers. Once someone experiences the difference—lying comfortably on the mat, breathing freely, moving without distraction—they never go back. The Mental Shift: Valuing Your Practice Here’s the bigger picture: choosing the right gear isn’t just about avoiding pain. It’s about valuing your practice enough to set yourself up for success. You wouldn’t show up to a dance performance in stiff jeans. You wouldn’t run a marathon in flip-flops. And you shouldn’t come to Pilates mat in a regular bra. Your costume matters because your practice matters. Conclusion Pilates is about creating strength, balance, and freedom in the body. But to access all of that, your body needs the right environment—and yes, that includes your clothing. A regular bra has no place in Pilates mat class. It will hurt your back, restrict your breathing, and distract from the flow. Choosing the right sports bra, with the right fit and fabric, sets the stage for comfort, performance, and a pain-free practice. So next time you head to class, take a moment to think about your costume. Give your body the gift of comfort. Because in Pilates, as in life, the details matter. And when the details work for you, the whole experience transforms.
