Quick answer: Cycle syncing means tracking your menstrual cycle and adapting your exercise, food and rest to its four phases: menstrual (week one, rest and iron-rich foods), follicular (week two, higher energy and strength training), ovulatory (week three, peak energy and high-intensity movement) and luteal (week four, slow down with low-impact activity). It is a flexible tool, not a strict rulebook, and can help you anticipate tougher days.
Hey, it's Aunt Julie here, ready to talk about periods. The irony is that this is a process your body goes through every month, one that consumes a great deal of your time, emotional energy and brain space for the best part of 40 years of your life, and no one thought to put some tools in your kit. Well, darling, here I am, ready to share my knowledge.
What is cycle syncing?
The premise of cycle syncing is that you closely track your monthly cycle and record how you feel, including your symptoms and overall mood. This can be done through journaling or using any number of apps. By tracking your symptoms, you can adapt your needs throughout the month and find a rhythm of exercise and a nutrition-centred, supportive diet. If you suffer from endometriosis or PMDD, this can be especially helpful.
Week one
The body: this week is when your body sheds the uterine lining and you are on your period. This lasts, on average, 3 to 7 days. The feeling: your energy is at its lowest as oestrogen and progesterone are at their lowest levels, and you may notice skin changes, fatigue, breast tenderness, bloating, cramping and mood swings. Supporting week one: rest and gentle movement like yoga, walking or swimming; prioritise iron, omega-3 fatty acids, vitamin B, magnesium and fibre.
Week two
The body: the follicular phase, when your body thickens the uterine lining and increases FSH, oestrogen and testosterone after your period ends. The feeling: often the most energetic time in the cycle. Supporting week two: hiking, bike rides and strength training; focus on lean proteins, non-starchy vegetables, healthy fats and anti-inflammatory foods.
Week three
The body: the ovulation phase, when an egg is released. The feeling: a boost in energy, concentration and sex drive. Supporting week three: high-intensity workouts like hot yoga, spin or dancing, plus high-fibre foods, whole grains and antioxidant-rich berries and nuts.
Week four
The body: the luteal phase, when oestrogen and testosterone decline while progesterone rises. The feeling: energy declines, with food cravings and a need to slow down. Supporting week four: switch to low-impact activities like walking, restorative yoga, Pilates or swimming. PMS symptoms such as breast tenderness, cramping and mood changes may appear. Balance your plate with healthy fats, complex carbohydrates and fibre.
The takeaway
Cycle syncing is simply a tool, one that can help ease some of the physical pain and emotional burden that come with being a menstruating person. If you give it a go, please write to me and let me know if it radically changes your life. With bountiful boldness, Aunt Julie x
Frequently asked questions
What is cycle syncing?
It's the practice of tracking your menstrual cycle and adapting your exercise, food and rest to each of its four phases (menstrual, follicular, ovulatory and luteal) to work with your changing energy and hormones rather than against them.
Does cycle syncing actually work?
Evidence is still emerging, but many people find that matching activity and nutrition to their cycle helps them manage energy, mood and symptoms. Think of it as a flexible tool, not a strict rulebook.
How do I start cycle syncing?
Begin by tracking your period dates, energy, mood and symptoms for a couple of months, in a journal or an app, then gently adjust movement and meals to suit each phase.
Can cycle syncing help with PMDD or endometriosis?
Tracking can help you anticipate tougher days and plan rest and support around them. It isn't a treatment, though. If you have severe symptoms, please speak to your GP.
