MEGAN LINK

Fitness has been a lifelong passion of mine. After competing in multiple sports growing up, I spent years running marathons and half marathons before discovering my love for strength training, functional fitness, HIIT, and kettlebells.

Following a serious back injury in 2022, I became even more committed to understanding movement, recovery, and long-term health. That journey led me to earn my NASM Certified Personal Trainer (CPT) certification in 2023 and my NASM Nutrition Certification in 2024.



I love challenging HIIT workouts and a little friendly competition, but I'm most passionate about helping people build strength, move well, and stay active for life. You'll usually find me at EnergyX coaching or taking classes, and when I'm not in the gym, I lead global brand and marketing initiatives for one of the world's leading technology companies. Outside of work, I enjoy exploring San Antonio with my husband and our three rescue dogs or getting lost in a good book.
