Exercise during your period: is it good, and what works best?
Yes, exercise during your period is safe and often helps. A Cochrane review found regular exercise, about 45 to 60 minutes three times a week, may cut period pain by a meaningful amount. Performance may dip trivially in the first days, but most people can train as normal. Go by feel: walking, yoga and easy cardio suit heavy days; rest when you need it.
Is it OK to work out on your period?
Yes. There's no medical reason to stop exercising during the menstrual phase, and for many people moving helps. You can swim (with a tampon or cup), run, lift, dance or do yoga, including inversions. What changes is how you feel, and that's personal. Some people set personal bests on day 2. Others need the sofa. Both are fine.
What the research says
| Question | What studies found |
|---|---|
| Does exercise help period pain? | A 2019 Cochrane review of 12 trials found regular exercise may reduce period pain by about 25 points on a 100-point scale. Evidence quality was low, but the effect was large and consistent. |
| How much? | Studies used about 45 to 60 minutes, three or more times a week, across the month. Intensity didn't seem to matter: yoga and stretching helped as well as aerobics. |
| Does your period hurt performance? | A 2020 meta-analysis of 78 studies found performance might be trivially lower in the early follicular phase (your period). The effect was so small and variable that the authors recommended a personal approach, not rules. |
| Does it affect strength gains? | A 2023 review found no clear evidence that cycle phase changes strength performance or muscle growth from training. |
The takeaway: you don't need to plan training around your period for physical reasons. You do want to plan around symptoms like cramps, heavy flow, poor sleep and low energy, if you have them.
Best exercise on your period
On heavy, crampy days
- Walking, especially outside. Gentle, warming, and good for mood.
- Yoga or stretching. Child's pose, cat-cow, reclined butterfly, supine twists and legs up the wall are favorites for cramps and low back ache.
- Easy cycling or swimming, if you feel comfortable.
- Pilates or mobility work at an easy pace.
On lighter days
Whatever you usually do: running, strength training, classes, team sport, HIIT. Many people feel stronger from day 3 onward as bleeding eases and estrogen starts to rise.
Dark leggings, a period-proof layer or cup for long sessions, a heat pack for after, and water. If you take ibuprofen for cramps, take it with food. Eat something before exercise if you're low on energy.
If you compete or train seriously, keep a simple log of period days, sleep and how sessions felt. Many athletes find a pattern worth planning around, such as needing a longer warm-up on day 1 or extra fuel on heavy days, even though group research shows little average effect.
Exercise and period mood
Movement is one of the most reliable mood lifters there is, and that holds on period days too. A 20-minute walk when you feel flat often does more than you expect. That said, rest is productive. If your body is asking for a lighter day, honoring that is part of a healthy routine, not a failure. Read more about mood during your period and being tired on your period.
Log energy alongside your period for a few cycles. Lulu shows which days you usually feel strong and which feel heavy, so you can plan hard sessions where they fit.
Exercise across the whole cycle

When to rest or check in with a doctor
Rest and see a doctor if you feel dizzy or faint during exercise, if bleeding is very heavy (soaking protection every 1 to 2 hours), or if period pain is severe enough to stop you moving. If you train hard and your periods become irregular or stop, talk to a doctor: it can be a sign of low energy availability, which affects bones and hormones.
Frequently asked questions
Is it bad to exercise on your period?
No. Exercise is safe on your period and may ease cramps and lift mood. Adjust intensity to how you feel.
Does working out on your period help cramps?
Regular exercise across the month may reduce period pain, according to a Cochrane review. On the day, gentle movement and stretching help many people.
Can I lift weights on my period?
Yes. Research hasn't found that cycle phase meaningfully changes strength. If you feel weaker on heavy days, lighten the load and keep good form.
What yoga poses help period cramps?
Child's pose, cat-cow, reclined butterfly, supine twists and legs up the wall are gentle options many people find soothing. Inversions are safe if you're comfortable.
Can you swim on your period?
Yes. A tampon, menstrual cup or period swimwear keeps you protected, and water pressure slows flow a little while you swim. Swimming is a gentle option on crampy days.
