  • You wake up unsure whether today is a "good day" or a "bad day" - and dread the guesswork of whether to train at all.
  • Generic plans ignore your flares, energy crashes, and unpredictable symptoms - so you either push through and pay for it for a week, or skip it and watch your hard-earned progress slip away.
  • You want to stay strong and active but aren't sure what's safe on the harder days - and you're done with the guilt of rest days.
  • You believe movement is medicine - you just need a clear roadmap that flexes around your condition, not against it.

Hi, I'm Amy

Hi, I'm Amy - founder of Refinery Strength Collective, NASM-CPT, coach, mom, and believer in grit built over time.

I know firsthand what it feels like to live in a body that doesn't always cooperate. After being diagnosed with Hashimoto's, I spent years feeling like fitness either ignored my reality or pushed me into burnout.

I created the Flare Day Cheat Sheet because I got tired of watching strong women sideline themselves unnecessarily on bad days - or push too hard and pay for it for a week. Today, I'm stronger as a mom, wife, and coach, and this tool is the roadmap I wish every client had from day one.
