“After two kids, I never thought I’d feel this strong again. Rachel Stone helped me rebuild my body and confidence.”
Sara Chen
Postnatal Reboot - November 2025
Meet your Founder & Head Coach
Hi, I'm Jared
For years, I thought strength meant doing more — training harder, eating cleaner, sleeping less. I pushed through exhaustion, believing discipline would bring freedom. It didn’t.
When burnout finally forced me to slow down, I started listening. I studied how movement, hormones, rest, and mindset work together — and rebuilt my strength through awareness, not pressure.
Now I help women do the same: feel capable and confident again without sacrificing themselves to get there. My approach blends science and empathy — habit-based, psychology-first, and built for lasting balance
