Strength holds up
Research shows performance is not reliably impaired during menstruation, and some lifters feel strongest in the follicular phase just after their period starts. Do not assume you have to go easy by default.
Keep lifting through your period if you feel able, adjust intensity to your energy, and know strength is not meaningfully reduced.
You can train normally on your period, and many find their strength holds or even peaks in the first half of the cycle. Listen to your energy: on heavy cramp or fatigue days, drop the intensity or volume and focus on movement, and on good days train hard as usual. Stay hydrated, keep iron rich foods in your diet since menstruation loses iron, and there is no need to stop lifting unless you genuinely feel unwell.

Cramps, fatigue, and poor sleep vary day to day. On rough days, cut volume or intensity and pick lower skill movements, on good days train fully. Let symptoms, not the calendar, set the effort.
Periods can lower iron and increase fatigue, so prioritise iron rich foods, hydration, and sleep. Light movement can also ease cramps by boosting blood flow, so training may actually help.
See a doctor if you have unusually heavy bleeding, severe or worsening cramps, or feel faint and short of breath, as these can signal anaemia or other issues that need attention.
