Experts warn against viral cycle syncing fitness trend

A growing social media trend known as ‘cycle syncing’ is encouraging women to adjust their exercise routines based on the phases of their menstrual cycle. Popularized on platforms like TikTok and Instagram, the concept suggests specific activities for different stages: lighter exercises like walking or Pilates during menstruation, increasing intensity during the follicular phase, high-intensity or strength training around ovulation, and returning to lower intensity during the luteal phase.

However, health experts warn that there is insufficient scientific evidence to support these rigid exercise prescriptions. Kelly McNulty, a researcher at Leeds Beckett University specializing in menstrual cycles and physical activity, describes the trend as being ‘based on marketing, rather than any kind of research or evidence.’

Experts emphasize that menstrual cycles are highly individual and can vary significantly between different women and even between different cycles in the same woman. This variability makes generalized social media advice difficult to apply, particularly for those with irregular cycles or those using hormonal contraception. Professionals suggest that individuals should listen to their own bodies rather than following strict, generalized rules found online.
