Meet the Soul Behind LumiSoul
Nervous System-Based Fitness & Online Coaching
Hi, I’m Sierra Prewitt — founder of LumiSoul and nervous system-based online coach for women who’ve tried everything and still feel stuck.
Like so many of my clients, I spent years doing all the “right things” — cutting calories, training harder, trying every plan — yet my body pushed back. Burnout, hormone crashes, 50 pounds of weight gain, and thousands of dollars on doctors left me feeling broken and dismissed.
That struggle is why I do what I do now. Because I know what it’s like to live in a body that feels like it’s fighting you — and I know what it takes to finally turn it around.
Today, I help women rebuild trust with their bodies, lose stubborn fat, and heal from the inside out using the Root of Results™ Method: a framework built on nervous system safety, science, and sustainability.
This isn’t about extremes or quick fixes. It’s about creating long-term results that feel effortless because your body finally works with you instead of against you.
