2-week core strength program to improve your core stability and confidence through breathwork.

If you’re ready to build a more supportive core and a mid-section you feel confident in…
Then you’re in the right place!

How would it feel to sit up a little taller and move from a place of inner strength and confidence?

Pretty good right?!

This isn’t just a 2-week program

It’s a life-changing journey that empowers you with skills to activate your core muscles through the incredible power of breathwork.

With BreathCore you will:

  • Learn how to better support your spine with your core, which often alleviates a lot of joint pain.
  • Gain a deeper connection to your center of gravity, feel more balanced and move with more ease.
  • Master the art of directing your breath in a way that moves energy, releases tension and cultivates inner strength.
“BreathCore taught me how important my breath is for my overall health and well-being. I learned that without proper breathing, any other exercise program you are doing will not be nearly as effective. One of my favorite things about this program is that it is easily digestible, with just a small time investment each day and I can do it on my schedule. BreathCore has given me tools to slow down, be more mindful and has had a major impact on my energy levels. I didn’t expect it, but even my sleep has dramatically improved!”

Here’s what Cass has to say about this transformative program:

“Since BreathCore, I am more connected to my core during my yoga practice and I can feel my core coming online during my day-to-day activities. It’s amazing to be able to feel my breath throughout my entire torso! BreathCore is good medicine for the body. If you’re looking for a program to help you strengthen your core, while also incorporating techniques to help you be more mindful – try BreathCore!”

“Jessi McMaster’s delivery and knowledge is outstanding. I joined her BreathCore program because I was looking for something to help me reduce my back and joint pain. I knew breath would help, but I wasn't sure how. Through BreathCore, I learned how breath has a major impact on not just my core strength, but my overall body health. My pain is down significantly and I feel empowered because now I know how to breathe in order to keep it that way. I would absolutely recommend BreathCore!”

Rethinking Core Strength

Despite what we’ve been told, the trick to feeling stronger and more confident in your core is not 100s of crunches or difficult exercises, like hanging leg raises. It also doesn’t require you to do more planks or lift heavy weights.

The Power of Breathing

Core strength and confidence come from understanding how to breathe. Seems simple, right? You’re breathing now, so why isn’t it working? The trick is knowing how to breathe to encourage flow and support with every movement daily.

Mastering Breath for Core Activation

BreathCore will teach you how to be a conductor of your breath. Direct the symphony of breath throughout your body to unlock new levels of strength and awareness within your core, enhancing your overall well-being.

BreathCore will provide you with LIFELONG TOOLS that will help you:

“Jessi's energy is inspiring and it is apparent that her well thought out workouts and precise cues are grounded in a deep knowledge of how our bodies work.

Here’s Kasie’s take on this life-changing program:

“I’m so thankful for Jessi and BreathCore! I joined this program when I noticed my gut was experiencing a lot of discomfort and it was actually keeping me from doing some of the fitness and everyday tasks that I wanted to do.

Jessi’s holistic approach to fitness and core strength has really helped me level up my own practice and my relationship to my health. Because of her BreathCore program, I now have a better understanding of the layers of my core and have a better understanding of how to connect my core, my breath, and my gut. I am so grateful for this new connection!

The short workouts made it super easy to fit it into my busy schedule. Jessi’s teaching style is easy to understand and the love, effort and attention she puts into this course is surreal.

Jessi has a way of inspiring and motivating you to continue to show up for yourself in a very positive way. If you’re looking for a program to help you breathe better and build core strength, try BreathCore, I’m sure you’ll love it!!!”

“I chose BreathCore because I was curious about the program and was looking for a different approach to wellness and staying fit. BreathCore taught me how important it is to breathe deeply, I learned different ways to breathe and how to use the capacity of the entire core to breathe - and I feel my core getting stronger! Plus, I now have simple breathing techniques to help me relax and calm my mind. If you’re thinking about doing BreathCore - try it! You will learn so much about how important breathing is to core strength.”
Cheryl B.
