Cycle Syncing Isn’t Magic ~ It’s Self-Awareness

Women’s health is nuanced. Hormones shift, energy ebbs and flows, and every body is different. And yet, every time a new trend hits social media, suddenly everyone’s an expert. Case in point: cycle syncing.

We teamed up with The Gist, and reactions were… intense. Some treated it like gospel; others insisted science has “debunked” it. The truth? It probably falls somewhere in between.

Cycle syncing is the idea that your workouts, meals, and self-care can follow your menstrual phases: menstrual, follicular, ovulatory, and luteal. Some people swear by it — tracking energy, scheduling high-intensity workouts when estrogen peaks, slowing down when PMS hits — because hormones really can influence energy, recovery, and how hard a workout feels.

But the research? It’s mixed. A 2020 review of 46 studies found some women fatigue less in the luteal phase, others in the follicular. Results vary depending on exercise type, muscle groups, and how phases are measured. Translation: your body might not match the “textbook," and that’s totally fine.

Here’s a quick cheat sheet:

~Menstrual: Gentle yoga, walking, restorative stuff (Netflix optional).
~Follicular: Higher-intensity workouts, strength training, longer runs.
~Ovulatory: Peak performance possible — HIIT, powerlifting, sprints — but watch those joints.
~Luteal: Lower-intensity cardio, pilates, mobility, recovery work.

Cycle syncing isn’t a strict rulebook. It’s a tool to notice patterns, stay consistent, and make exercise feel a little more supportive. Some days you'll crush it. Some days you'll lounge on the couch with a heating pad. Both are fine. The real win? Learning to trust your body, honor its signals, and move in a way that actually feels good — because that’s how lasting fitness, energy, and self-care happen.

Ask Clara: How do hormones fluctuate throughout the menstrual cycle?
