Core & Abs

Get started today!

Welcome to your go-to hub for all things core! Whether you’re looking to build strength, stability, or just feel that good kind of sore after a workout, this category has you covered. These classes range from bodyweight burners to minimal-weight moves, all designed to target your core from every angle—front, back, and sides. As a NASM-certified coach, I’ve programmed each session to be both effective and safe, supporting your posture, strength, and overall performance in and out of the gym. No fluff—just intentional movement you can feel. Add these on to the end of your lift, stack a few for a core circuit, or press play for a quick standalone sweat. However you use them, your core will thank you. Let’s get strong from the center out.

About Chelsea Hofer

Hiya!

I'm Chelsea Hofer (@chelseasyoga) I’m a mom of three teens and a baby boy and found yoga in 2014! I was never a gymnast, dancer, or competitive athlete but found myself deeply drawn to yoga after my first class. It created a sense of calm and quiet that my overly congested mind craved. I became certified to teach in April '15 (RYT 200) and my passion for sharing my pracitice and teaching others took over. I later earned my RYT 500 & CPT. I teach my classes online and host retreats around the world and on five continents. At 40, I started weight training, cycling, and recently started running! I continue to chase what makes me feel strong and continue to explore new curiosities (i.e. running). Movement can be whatever you want it to be and for anyone. It is such a privilege to move our bodies, find new ways in which we grow, and prove to ourselves we can always rise up stronger! I am so glad you're here!
