Training during your period is not a question of whether you should. It is a question of how, and the answer changes depending on where you are in your cycle, how you're feeling that day, and what kind of session you had planned. There is no single rule that applies to every body every month.
Why energy shifts across your cycle
Hormone levels change through the menstrual cycle, and those shifts affect energy, strength and recovery differently at different points. Many people feel stronger and more resilient in the days after their period ends, through to ovulation, and notice more fatigue or lower tolerance for high-intensity work in the days just before and during bleeding. This is common, not universal. Some people notice almost no difference. Both are normal.
During your period: what tends to help
Lighter intensity is not a downgrade. If heavy lifting or high-intensity intervals feel harder than usual, that is real, not a mindset problem. Dropping load or intensity for a few days protects the quality of the sessions either side of it.
Walking and steady cardio often feel better than expected. Movement can ease cramping for some people by improving blood flow, even when the idea of training feels unappealing at the start.
Core work and heavy compression around the abdomen can feel uncomfortable. If a particular exercise or piece of kit is aggravating cramping, swap it rather than push through it. There is no reward for finishing a session that made things worse.
Rest is a legitimate choice. If a session isn't happening today, skipping it does not undo a training block. One missed session changes nothing over a month.
What helps day to day
Comfortable, non-restrictive kit around the waist and hips. Tight waistbands sitting directly on a bloated or cramping abdomen make a session harder than it needs to be. Our legging collection includes a range of rise heights if a lower or higher waistband feels better on a given day.
A sports bra that doesn't add pressure you don't need. Breast tenderness is common in the days before and during a period. A slightly less compressive option from our sports bra collection can make a real difference on those days specifically, even if it isn't your usual choice.
Heat, hydration and basic pain relief are not weakness. A heat pad before a session, staying on top of water intake, and taking whatever pain relief works for you if cramping is significant are all reasonable parts of a normal training routine, not signs you should have skipped the gym.
Signs you should scale back further, or stop
Severe pain that doesn't respond to your usual approach, dizziness, or symptoms that are unusual for you are reasons to stop and check in with a doctor, not reasons to push through for the sake of a training streak. Period pain that consistently disrupts daily life, not just training, is worth raising with a GP rather than just working around.
The bigger picture
Consistency across a month matters more than any single session, and factoring your cycle into training is not the same as skipping training. Adjust intensity when you need to, keep moving when you can, and treat rest during a harder few days as part of a sensible plan rather than a failure of one. If getting into a routine at all still feels like the bigger hurdle, How to Start Going to the Gym When You're Nervous covers building that habit from a calmer starting point.
Your body is not the same every week of the month, and training that accounts for that tends to hold up better over a year than training that ignores it.
