Hello Friend,
I have some exciting news to share with you! This is a little different from my usual blog post, where I share information, teach something new, and often include one of my videos. This time, I wanted to send you a special announcement about my new book, Core Strength Is Your Superpower: It’s Not a Cliché, and Here’s Why.
I’m so excited to finally share it with you!
The book is now available on Amazon in both Kindle and paperback editions. You can also order a signed copy directly through my website.
In Core Strength Is Your Superpower: It’s Not a Cliché, and Here’s Why, award-winning fitness educator Tracy L. Markley explains why the core is one of the most important foundations of human movement—and why thinking of it as simply a “six-pack” misses the whole picture.
Your core is made up of 29 muscles, including deep muscles that help stabilize your spine, pelvis, and torso. Throughout this book, Tracy explains how your core connects to the rest of your body and why a strong center matters for functional movement.
You will learn about the relationship between core strength and:
I also explain some of the deeper muscles that are often overlooked, and other muscles that contribute to the body's stability and movement.
The book includes powerful real-life stories from my years of working with clients, including older adults and stroke survivors. These stories show what can happen when people understand how to engage their core, improve their posture, and consistently work on movement.
I share four powerful core-strengthening exercises with different levels and options, including standing, balance work, and seated variations. The book also includes the core muscle illustrations so you can see how your “superpower team” connects throughout your body.
This is not simply a book about getting stronger abs.
It is about understanding why your core is your superpower to your entire body—and how that knowledge can change the way you think about posture, balance, walking, exercise, and movement.
Your core is your superpower. It’s not a cliché. I show you why.
With warmth and care,
Tracy Markley
