Breathe Easy: 7 Exercises to Strengthen Your Hidden Breathing Muscles

The Surprising Key to Better Endurance

Last week, a client came to me frustrated about her shortness of breath during workouts. Her lungs were healthy, and she was in great shape otherwise. So what was going on? The culprit was hiding between her ribs.

Intercostal muscles are the unsung heroes of breathing and athletic performance. These thin layers of muscle between your ribs control how your ribcage expands and contracts. And let me tell you, when they're weak, it can feel like you're breathing through a straw.

Why do most people never train them? Well, they're easy to overlook. But I've seen firsthand how strengthening these muscles can be a game-changer for breathing power, core stability, and even posture.

What the Research Actually Shows

The science is pretty clear on this one. Studies in the Journal of Applied Physiology suggest that targeted respiratory muscle training can increase ventilatory efficiency and reduce the oxygen cost of breathing during exercise. In plain English? You'll breathe easier and use less energy doing it.

Here's what that means for you:

• Better endurance - you'll fatigue slower during long workouts
• Faster recovery between high-intensity intervals
• Improved core stability for lifting and sports
• Potentially reduced back pain due to better postural support

Foundation Breathing Exercise: Lateral Rib Expansion

Let's start with the basics. This exercise is the foundation for all intercostal training:

1. Sit or stand comfortably, placing your hands on your lower ribs.
2. Inhale slowly, focusing on expanding your ribs outward into your hands.
3. Feel the stretch between your ribs as they separate.
4. Exhale with control, drawing your ribs back together.
5. Perform 10-15 repetitions, 3 sets.

This exercise builds awareness of how your intercostal muscles work while improving rib mobility. Master this before moving on to more challenging variations.

Progressive Intercostal Strengthening Exercises

Once you've got the basics down, it's time to add some resistance. Here are two of my favorite exercises for building serious intercostal strength:

1. Resistance Band Rib Pulls

1. Wrap a resistance band around your ribcage at mid-chest level
2. Cross your arms over your chest, gripping the band ends
3. Inhale against the band resistance, focusing on expanding your ribs outward
4. Hold for 3-5 seconds, then exhale with control
5. Complete 12-15 repetitions for 3 sets

2. Weighted Side Bends with Breathing

1. Hold a light dumbbell in one hand, opposite hand on hip
2. Lean away from the weighted side while inhaling deeply
3. Focus on expanding the ribs on the stretched side
4. Return to center while exhaling completely
5. Perform 10 reps each side, 3 sets

These exercises might feel a bit awkward at first. That's normal! You're targeting muscles that rarely get direct attention. Stick with it, and you'll start to feel a difference in your breathing power within a few weeks.

Advanced Rotational Power Training

Ready to take it up a notch? These dynamic movements integrate intercostal strength with functional movement patterns:

1. Medicine Ball Spiral Throws

1. Stand sideways to a wall, holding a medicine ball at chest height
2. Rotate away from the wall, inhaling deeply and expanding your ribs
3. Explosively rotate towards the wall, throwing the ball as you exhale forcefully
4. Catch the rebound and repeat
5. Perform 8-10 reps each side, 3 sets

2. Cable Woodchoppers with Breath Focus

1. Set a cable machine to chest height
2. Stand sideways to the machine, feet wider than shoulder-width
3. Grasp the handle with both hands, rotate away while inhaling deeply
4. Pull the cable across your body, rotating and exhaling forcefully
5. Control the return, inhaling as you rotate back
6. Complete 10-12 reps each side, 3 sets

Putting It All Together

In my practice, I've seen clients transform their athletic performance by incorporating these exercises just 2-3 times a week. Start with the foundation exercise, then gradually add in the more advanced movements as you build strength and awareness.

Remember, consistency is key. Your intercostal muscles adapt relatively quickly, but like any training, you need to keep challenging them to see continued improvement.

So, what does this mean for your workouts? You might not see dramatic changes overnight, but within a few weeks, you should notice:

• Less breathlessness during high-intensity exercise
• Improved posture and core stability
• A greater sense of control over your breathing
• Potentially better performance in sports requiring rotational power

Give these exercises a try, and let me know how they work for you. Your lungs might be healthy, but it's those tiny muscles between your ribs that could be the secret to unlocking your next level of fitness.
