If you think only weights build muscle, here’s what yoga can do

yoga and muscles

If you’re someone who believes that the only way to build muscle is by lifting heavy weights, I get it.

I used to think the same.

The image of a strong, muscular physique often comes hand-in-hand with barbells, dumbbells, and a gym full of heavy equipment.

But what if I told you there’s another way to build strength? One that doesn’t require a gym membership or stacks of iron plates.

Yoga.

Yes, yoga.

It’s more than just stretching or calming your mind.

In fact, yoga has a surprising ability to build muscle, tone your body, and improve your overall strength in ways that might surprise you.

Let’s dive into how yoga works for building muscle, and why you might want to rethink your approach to fitness.

The surprising science of muscle building in yoga

When you think of building muscle, resistance is the key factor.

Weightlifting provides that resistance in the form of external weights, but yoga does the same thing using your own body weight.

Take poses like Plank, Warrior II, or Chaturanga (yoga’s version of a push-up). These poses require you to hold your body weight in challenging positions, engaging your muscles in ways that create tension and, ultimately, growth.

Here’s the thing: research supports this.

A study published in the International Journal of Therapy and Rehabilitation found that yoga improves muscular strength, endurance, and flexibility. It even rivals traditional resistance training in some areas.

Why yoga builds strength differently

When I first started practicing yoga, I was shocked at how hard it was to hold poses like Chair Pose or Crow Pose.

These positions aren’t just about balance. They force your muscles to work together, recruiting stabilizers you didn’t even know existed.

Unlike traditional weightlifting, which often isolates specific muscle groups, yoga focuses on compound movements.

This means you’re engaging multiple muscle groups at the same time, which helps improve functional strength — the kind you use in daily life.

For example:

  • Holding a Plank strengthens your core, shoulders, and arms.
  • Moving through a Sun Salutation works your entire body in a fluid, strength-building sequence.

You’re not just building muscle — you’re building balance, coordination, and endurance, too.

5 ways yoga can help you build muscles

1) Flexibility and strength

You’ve probably heard the term ‘flexibility’ thrown around in a yoga context.

But did you know that flexibility and muscle strength go hand in hand?

When we think about weight lifting, we usually picture bulky muscles and heavy weights. But strength isn’t just about lifting the heaviest dumbbell in the gym.

Yoga helps build lean muscle, which is just as strong and much more flexible than the bulkier muscles you might associate with weight lifting.

So yes, yoga can indeed build muscle.

And the best part?

It does so while promoting overall body wellness and flexibility.

2) Engages your entire body

Here’s something you might not know:

Unlike weightlifting, which tends to focus on individual muscle groups, yoga is a full-body workout.

Every pose in yoga engages multiple muscle groups at once, promoting balanced strength throughout your entire body.

This means you’re not just working on one area at a time, but strengthening your whole body in harmony.

This holistic approach can lead to better posture, improved balance, and less risk of injury.

3) Improves muscle endurance

Weightlifting is all about short, intense bursts of effort.

But what about exercises that require prolonged effort?

Well, yoga poses are often held for extended periods of time, which can significantly improve muscle endurance.

In other words, your muscles aren’t just getting stronger; they’re also learning to sustain that strength over a longer period of time.

This kind of endurance training can enhance your performance in other physical activities and sports, while also making everyday tasks easier.

So if you think that only weights can build muscle, remember – yoga can do quite a lot more.

4) Healing and recovery

There was a time when I pushed myself too hard in the gym. I ended up with a shoulder injury that had me benched for weeks. It was frustrating; all that progress, halted.

During my recovery, I turned to yoga. At first, it was just a way to stay active. But soon, I realized it was helping me heal.

Yoga’s gentle stretches and poses helped increase blood flow to my injured shoulder, aiding in its recovery. The focus on body awareness made me more in tune with my limits, helping me avoid future injuries.

Now, even though I’m back to my regular gym routine, I still include yoga sessions for their healing and restorative benefits.

It’s not just about muscle building — it’s about keeping those muscles healthy too.

5) Promotes mental strength

Building muscle isn’t just a physical journey; it’s a mental one too. And this is where yoga really shines.

Yoga encourages mindfulness, focus, and discipline.

It teaches you to stay present, to breathe through discomfort, and to push your limits in a safe and controlled manner.

These mental strengths can be invaluable when it comes to muscle building.

They can help you stay consistent with your workouts, push through plateaus, and maintain a positive mindset even when progress feels slow.

Yoga’s secret weapon: Isometric holds

Have you ever tried holding Warrior II for a full minute?

If you have, you know how much your thighs burn.

That’s because yoga incorporates isometric holds — positions where your muscles contract without changing length.

Isometric exercises are incredibly effective for building strength.

When you hold a pose, your muscles work harder to maintain stability, creating micro-tears in the muscle fibers that repair and grow stronger over time.

For me, holding these poses was a humbling experience.

I thought I was strong from weightlifting, but yoga showed me how much strength I still needed to develop, especially in my core and stabilizing muscles.

Yoga builds more than muscle

If you’re chasing strength alone, yoga still delivers.

But it also offers something weightlifting often overlooks: flexibility, balance, and mobility.

Think about it.

What’s the use of strong muscles if they’re tight and prone to injury?

Yoga combines strength-building with stretching, keeping your muscles supple and improving your range of motion. This balance reduces your risk of injuries—not just in yoga, but in any physical activity you do.

For example:

  • Downward Dog stretches your hamstrings and calves while strengthening your arms and shoulders.
  • Tree Pose builds strength in your legs while enhancing balance and focus.

Yoga doesn’t just make you strong; it makes you resilient.

Can yoga replace weightlifting?

The short answer: it depends.

If your goal is to bulk up like a bodybuilder, yoga might not be enough. Traditional weightlifting provides the high levels of resistance needed for significant hypertrophy (muscle growth).

But if your goal is to build lean muscle, improve functional strength, and enhance your overall fitness, yoga can absolutely stand on its own—or complement your weightlifting routine.

In fact, many athletes use yoga to enhance their performance in the gym.

Improved flexibility and mobility make weightlifting safer and more effective, while yoga’s core-strengthening benefits translate directly to better lifts.

How to get started with yoga for strength

If you’re new to yoga, you don’t need to dive into advanced poses right away. Start with foundational poses that build strength gradually.

Here are a few to focus on:

  • Plank Pose: Strengthens your core, shoulders, and arms.
  • Warrior II: Builds endurance and strength in your legs.
  • Boat Pose: Engages your core and hip flexors.
  • Chair Pose: Works your quads, glutes, and lower back.

Practicing these poses consistently—even for just 10-15 minutes a day—can create noticeable improvements in your strength over time.

Final thoughts: Why not both?

Here’s the beauty of yoga and weightlifting: they don’t have to be mutually exclusive.

In fact, they complement each other beautifully.

Weightlifting builds raw strength, while yoga enhances balance, flexibility, and recovery. Incorporating both into your routine gives you the best of both worlds—muscles that are not only strong but also functional and flexible.

Personally, combining yoga with resistance training has made me stronger in ways I never imagined. I can lift heavier weights, move more freely, and recover faster—all thanks to yoga.

So, if you’ve always thought of yoga as “just stretching,” I challenge you to give it a try.

It might surprise you, as it did me, how much strength it builds — not just physically, but mentally and emotionally, too.
