If you've spent any time on women's health content online, you've probably come across advice that sounds something like this:

"Rest during your period. Train like a man during your follicular phase. Push your hardest at ovulation. Stick to yoga and light weights during your luteal phase."

It's everywhere and it's not entirely wrong. But it's not entirely right either. And for many women, it's actually doing more harm than good.

The problem with one-size-fits-all advice

The biggest issue with most cycle syncing content? It tells you how you should feel, rather than meeting you where you actually are.

Research analyzing cycle syncing content on TikTok found that the majority of creators recommended syncing specific types of exercise to cycle phases but very few cited any scientific evidence, and many oversimplified a complex body of literature.(doi: 10.1111/psrh.70004)The reality is that experience varies enormously from person to person. Some women feel incredible at ovulation. Others feel off. Some have minimal symptoms throughout their entire cycle. Others are significantly impacted. There is no universal script for how your body moves through its cycle — and advice that ignores that variation isn't serving you.

What the research actually says

Here's where it gets interesting: a 2023 umbrella review found no meaningful influence of menstrual cycle phase on acute strength performance or adaptations to resistance exercise training. In other words, your body's ability to build strength and muscle doesn't dramatically shift based on where you are in your cycle. (doi: 10.3389/fspor.2023.1054542)

A 2020 meta-analysis of 78 studies concluded that exercise performance might be only trivially reduced during the early follicular phase, and noted that current data on hormones and exercise performance remains conflicting, with no consensus that performance is meaningfully affected by cycle phase.

This doesn't mean your cycle has zero impact on how you feel day to day - it absolutely can. But it does mean the sweeping recommendation to go easy for two or more weeks out of every month is not backed by solid science, and more importantly, it's not doing your health any favors.

Cutting your effort in half isn't a strategy, it's a setback

Think about what that advice actually looks like in practice. If you're following strict cycle syncing protocols, you could be operating at reduced intensity for more than half the year. That's not a recipe for progress. That's a recipe for staying stuck.

Exercise thrives on consistency. It's built week over week through a sustainable balance of effort and recovery — not dramatic swings driven by a calendar. If you find yourself so depleted that you genuinely need two weeks of recovery every single month, that's important information — but the answer isn't to accept it as normal. It's to get support.

The better approach: self-regulation

Rather than following blanket recommendations, the goal is to sync your exercise to how you actually feel — and that looks different for everyone.

Ask yourself: How did I sleep last night? Have I been eating enough? What's my stress load right now? These are the real variables. Your cycle is one input among many, not a rigid rulebook.

Note: if you're pregnant, postpartum, on hormonal birth control, or post-menopausal, this framework looks a little different for you, and that's worth a dedicated conversation.

Your cycle is a vital sign - not a 'problem'.

If you feel genuinely awful for most of your cycle and it's affecting your ability to move, function, and show up in your life — please hear this: that is not normal, and you do not have to accept it.

A healthy menstrual cycle should be regular, present, and come with minimal disruption. It is not meant to sideline you for weeks at a time. If you're struggling, there is support available, and you deserve to access it.

Have questions? I'd love to hear from you.

This is one of my favorite topics to dig into with patients and community members alike. Whether you're wondering how your cycle fits into your training, or you're dealing with symptoms that feel unmanageable, hit reply — I'm happy to talk through it with you.
With peace and love,
