Let’s exhale stress & set boundaries—together.


Hi Reader,

If you’ve ever felt like your time isn’t your own, your energy is constantly being drained, or your boundaries are just… not working—this is for you.

I'm inviting you to join me for something powerful, practical, and so needed right now:

💜 The Breathwork & Boundaries Series

This isn’t just about breathing deeply (although we’ll do plenty of that!). It’s about regulating your nervous system, reclaiming your energy, and finally setting boundaries that serve you—not stress you out.

Over 12 streamed classes led by world-renowned breathwork teacher Richie Bostock, you’ll learn proven techniques to calm, energize, and reset your body and mind. We’ll host everything on the Fitt app platform, so you can join from wherever you are.

🧘🏾‍♀️ And there’s more:

  • A 60-minute live midpoint group support session with me—Dr. Kourtney Sims, double board-certified physician and functional medicine guide through midlife.
  • A 75-page workbook with 12 self-guided tools to help you build, stretch, and maintain healthy boundaries in every area of life.
  • Support that’s actually doable—even with a full calendar.

You can register for the full series and move through each workbook tool at your own pace, with live sessions designed to leave you feeling grounded—not overwhelmed. In case you miss one of the live streamed classes we got you! There will be a replay every weekend of the breathwork classes for that week in case you need to catch up or you just want to review one of the sessions.

✨ Ready to breathe differently and live more freely?

Hi, I want to officially share something I’ve been putting together for the new year. It’s called the 7-Day 2026 Reset: Refresh, Restore, Renew, and it’s designed for people who want to feel better and not burned out as January begins. This isn’t a detox. It isn’t a diet. And it isn’t about doing everything “right.” Instead, over one week, we focus on foundational habits that support energy, digestion, sleep, stress regulation, and overall wellbeing by using practical strategies you can...

DR. KOURTNEY FUNCTIONAL & INTEGRATIVE GYNECOLOGY & OBESITY MEDICINE PHYSICIAN Hi there! As we head into January, I want to name something I see every single year in practice. Not a lack of motivation. Not people “falling off.” Not failure. What I see instead is physiology catching up after a month that quietly disrupts blood sugar, digestion, sleep, inflammation, and nervous system regulation. And then January arrives… and women blame themselves. If you’re feeling more tired than energized,...

Hello, friend! Let’s talk about your December physiology December has a way of illuminating every system in the body: your hormones, your stress response, your metabolism, your sleep, your gut… whether you’re 28, 38, 48, or 58. Every year in clinic, I watch women of all ages move through the holidays feeling: More wired at night More exhausted during the day More sensitive to sugar, alcohol, or poor sleep More reactive emotionally More aware of what their body has been whispering all year...
