Should You Sync Your Workouts with Your Menstrual Cycle?
Share
You've probably heard advice online saying you should "train with your cycle" — meaning, match your workouts to different phases of your menstrual cycle to get better results. This idea has grown popular, especially on social media, with claims that adjusting training to hormonal changes can improve strength or endurance. But what does science actually say?
What Is Menstrual Cycle–Based Training?
This approach suggests changing your workout type or intensity depending on where you are in your menstrual cycle. For example:
- Do more intense workouts during the follicular phase (the first half of your cycle).
- Focus on recovery or lighter exercise in the luteal phase (the second half).
- Avoid heavy workouts during your period due to possible fatigue and pain.
The idea is based on the fact that hormone levels — like estrogen and progesterone — rise and fall throughout the month. These hormones affect more than just reproduction; they also influence energy levels, muscle recovery, and even mood.
Sounds Logical, But Is It Proven?
Here’s the catch: research does not strongly support the idea that syncing workouts with your cycle gives better results than regular training. Some small studies have suggested slightly better strength gains when training more during the follicular phase. But these studies mostly involved untrained women, used small sample sizes, and often didn’t track hormone levels properly.
In fact, recent reviews of all the available studies found that menstrual cycle phase has little to no consistent impact on strength or endurance performance.
What About Symptoms?
It’s true that many women experience physical or emotional symptoms during their periods or the days leading up to them — things like cramps, fatigue, or mood changes. In these cases, adjusting your workouts based on how you feel can be helpful.
However, not every woman experiences these symptoms, and some can perform just as well throughout their entire cycle. So while listening to your body is always a good idea, there’s no need to follow a strict schedule unless it works for you.
So, What Should You Do?
Here are some practical takeaways:
- Track your cycle and your symptoms: Over time, you might notice patterns. If certain days make you feel more tired or uncomfortable, it’s okay to modify your training then.
- Don’t feel pressured to change your training: The science doesn’t currently support cycle-based training as superior. Traditional training programs still work well.
- Talk to a professional: If you have severe symptoms that affect your performance or daily life, speak to a doctor or gynecologist.
- Be flexible: Your body is unique. Focus on consistency, recovery, and adjusting based on how you feel — not just what the calendar says.
The Bottom Line
Menstrual cycle–based training might sound appealing, but right now, there’s not enough strong evidence to say it works better than regular training. It may help some women feel more in tune with their bodies, but it’s not a magic formula for improved performance. The most important thing? Keep moving, train smart, and listen to your body.
