## Quick answer

- Exercise on your period is safe and may ease cramps.
- Performance differences across the cycle seem small and personal.
- Periods stopping with heavy training needs a check-up.

Moving your body on your period is safe, and for many people gentle exercise actually eases [cramps](https://splash.care/learn/period-care/cramp-relief). The NHS lists yoga, swimming, walking and cycling as things that may help period pain. A Cochrane review of 12 small trials agreed that exercise might reduce period pain, although the evidence is low quality.

## What does the science say about performance?

A 2020 review pooling many studies found performance might be very slightly lower in the early [follicular phase](https://splash.care/learn/glossary/follicular-phase) (around your period) on average, but the effect was trivial, the evidence was low quality, and it varied a lot between people. A 2023 review of strength training found no clear influence of cycle phase on strength or muscle gains. In short: listen to your own body.

## Making it comfy

- [Tampons](https://splash.care/learn/period-care/products-compared), cups or discs are handy for swimming.
- Period pants or a pad plus dark leggings for the gym.
- Drink water and have a snack if you feel low on energy.
- Choose gentler sessions on heavy or crampy days if that feels better.
- The NHS aims for 150 minutes of [moderate activity](https://splash.care/learn/glossary/moderate-activity) a week for adults. A period is not a reason to skip it, but it is a fine reason to swap a session for a walk.

- **Period:** Gentle walks, yoga or swimming can soothe cramps.
- **Follicular:** Many people feel up for trying something new or harder.
- **Ovulation:** Energy often feels high. Warm up well.
- **Luteal:** Steady, moderate movement can help PMS symptoms, as the NHS suggests regular exercise for PMS.

**Myth:** You should avoid exercise or swimming on your period.

**Fact:** The NHS lists exercise as something that can ease period pain. Swimming is fine with a tampon or cup.

> **Splash says:** if heavy periods are making you tired or breathless during exercise, mention it to a GP. Low iron is common, easy to test for, and fixable.

### When to see a doctor

If you train a lot and your periods have become irregular or stopped, see a GP. The International Olympic Committee describes this as a possible sign of [REDs](https://splash.care/learn/glossary#reds), where you do not eat enough for the energy you use. It can affect bones, immunity and mood as well as periods, and it is treatable with support.

**Quick quiz:** You train hard and your periods stop for 3 months. What is the best next step?

1. Train harder
2. See a GP, because it can be a sign you are not getting enough energy
3. Ignore it, it is normal for athletes

Answer: See a GP, because it can be a sign you are not getting enough energy. Periods stopping with heavy training is common but not harmless. The IOC consensus statement lists missing periods as a warning sign of low energy availability, which can affect bone health, and it needs support.
