Thinking about holding off till the New Year to start your new routine?
As women, we often talk about our cycle as something to manage or work around. But the truth is: your hormones are one of your greatest tools. When you understand them, you can use your cycle to build habits that actually last.
Picture this: it’s January 1st. You’re motivated, determined, ready for a “new you.” Two weeks later? You’re exhausted, the routines feel impossible, and motivation has vanished.
Here’s what no one tells women: we set resolutions based on the calendar, not our biology. And that mismatch can set you up to fail before you even begin.
Your menstrual cycle has distinct hormonal phases that influence motivation, energy, learning, and stress resilience. When you try to launch a big new habit during a low-energy phase, it’s like planting seeds in winter and wondering why nothing grows.
The good news? Once you understand your cycle, you can work with your body, not against it and suddenly, your chances of success skyrocket.
The Calendar Lies. Your Hormones Don’t.
If January 1st lands during your luteal or menstrual phase, you’re starting your resolution at a biological low point:
- Energy dips
- Motivation drops
- Self-criticism peaks
- Resilience is reduced
This has nothing to do with discipline. It’s neurochemistry. Oestrogen and progesterone influence dopamine (motivation), serotonin (mood) and GABA (stress response). During low-oestrogen phases, starting a demanding new routine simply feels harder.
Science Can Change Everything
Your energy, cognition, and motivation shift throughout the menstrual cycle. Sometimes subtly, sometimes dramatically. That “gym feels impossible this week” feeling? It’s real, and can often be hormonal.
When you understand each phase, you can choose when to start, when to build, and when to rest or reflect. No more forcing. No more fighting yourself.
And to be clear: you can start a habit any day of the month. MUTU will always support “right now” as a perfectly good time.
But when you know what your cycle is doing, you can give yourself a better chance of making it stick.
The Four Phases of Habit Readiness
Menstrual Phase (Days 1–5): Reflection, Not Action 🤔
Hormones: Low estrogen + low progesterone
Impact: lower energy and heightened self-awareness.
Best for: clarity, values work, journaling, planning.
Not ideal for launching something new.
Try asking:
- Who do I want to become?
- What habit supports that version of me?
- What tiny change would feel grounding right now?
Follicular Phase (Days 6–14): Your Habit Launchpad ⭐
This is your moment. Rising estrogen boosts energy, optimism, motivation, and neuroplasticity. Your brain is primed to learn and adapt.
Best for: starting new habits, building routines, trying new skills.
Why?
- Rewards feel more rewarding (dopamine sensitivity increases)
- New neural pathways form more easily
- Confidence naturally rises
Aligning a “fresh start” with your follicular phase gives you both a psychological and biological boost.
Ovulatory Phase (Days 14–16): Amplify & Commit 🤝
Estrogen + testosterone peak. You’re social, confident, assertive.
Best for: accountability.
Tell someone. Share your intention. Put it in the diary. Confidence is high… use it, mama!
Luteal Phase (Days 17–28): Maintain, Don’t Launch 💪🏻
Energy dips, stress sensitivity increases, self-criticism can creep in.
Best for: maintaining what you’ve started, adjusting intensity, being kind to yourself.
Keep habits small and steady. Compassion is key here.
So… when should I start?
If you’re unsure, start with movement.
Not punishing workouts, not all-or-nothing January promises. Just simple, supportive movement that helps you sleep better, feel steadier, and trust your body again.
That’s exactly what MUTU is designed for. Our programmes meet you where you are—pregnancy, postpartum, perimenopause, or anywhere in between. No pressure. No perfection. Just the right movement for the body you’re in today.
How to Build a Movement Habit That Actually Sticks Start in your follicular phase
Track with the Phase app. Learn how to lean into those hormone fluctuations.
Make the first step tiny
Practise your MUTU breath whilst the kettle boils. Try 10 minutes of your workout whilst the washing machine finishes.
Anchor it to something you already do
Habit stacking makes consistency easier: “After I make my coffee, I’ll do a MUTU core session.”
Let your cycle set the pace
You’re not designed to move the same way daily – MUTU honours that.
- Follicular & Ovulatory: increase challenge
- Luteal: soften intensity
- Menstrual: rest intentionally
This is the definition of sustainable.

P.S. Everyone’s experience with menstruation is unique, so you might notice that your energy levels don’t always match the typical patterns described above. How you feel during each phase can also vary from one cycle to the next. It’s important to observe and adapt to your body’s signals, as your personal experience may differ.
