Why do I have no energy and get irritated before my period

A dip in energy and mood swings in the second half of the cycle are ordinary. This isn't about weak willpower.

What helps: lowering the intensity instead of dropping out altogether, adding sleep, and not running a harsh calorie deficit on those days. Cravings for something sweet make sense too — they're easier to ride out if you're not hungry.

When your cycle sits next to your workouts in the app, the dip stops being a surprise: you can see it coming and plan a calmer week.
