Right, let’s talk about PMS and exercise. Because if one more person tells you to “just go for a run” when you’re dealing with cramps, bloating, mood swings, and feeling like you’ve been hit by a lorry, you might actually scream.

But here’s the thing: exercise can genuinely help with PMS symptoms – just not in the “just push through it, hun!” way that wellness Instagram would have you believe. There’s actual science behind this, and understanding what’s happening in your body can help you figure out what type of movement actually helps versus what makes you feel worse.

So let’s dig into the research, talk about what actually works, and acknowledge that some days, the sofa and a hot water bottle are genuinely the right choice.

What Is PMS, Actually?

Premenstrual syndrome (PMS) refers to the physical and emotional symptoms that show up in the week or two before your period. About 75% of women experience some PMS symptoms, and for about 5-8%, it’s severe enough to significantly impact daily life (that’s called PMDD – premenstrual dysphoric disorder).

Physical symptoms include:

• Bloating
• Breast tenderness
• Headaches
• Fatigue
• Food cravings
• Sleep problems
• Joint or muscle pain
• Digestive issues

Emotional/mental symptoms include:

• Mood swings
• Irritability or anger
• Anxiety
• Depression
• Brain fog
• Reduced concentration

If you’re nodding along thinking “yep, that’s me every month,” you’re not alone. PMS is incredibly common, and it’s not just “being hormonal” – it’s a real physiological response to hormonal fluctuations.

The Science: How Exercise Helps PMS

There’s actually quite a bit of research on exercise and PMS, and the results are pretty consistent: regular physical activity can reduce the severity of PMS symptoms. But how?

Endorphins (The Natural Mood Boosters)

Exercise releases endorphins – your body’s natural “feel-good” chemicals. These don’t just improve mood; they also have pain-relieving properties. So when you’re dealing with cramps, headaches, or that general achey feeling, endorphins can genuinely help.

Research shows that women who exercise regularly report less severe PMS symptoms, particularly mood-related ones like irritability, anxiety, and depression.

Blood Sugar Regulation

During the luteal phase (the two weeks before your period), your body’s insulin sensitivity decreases. This means your blood sugar is more likely to spike and crash, which worsens mood swings, energy crashes, and cravings.

Exercise improves insulin sensitivity, helping keep your blood sugar more stable. This can reduce those extreme hunger pangs and the emotional rollercoaster.

Reduces Inflammation

PMS involves inflammation, which contributes to pain, bloating, and that general “blah” feeling. Regular exercise has anti-inflammatory effects that can help reduce these symptoms over time.

Improves Sleep

Many women struggle with sleep during PMS, whether it’s trouble falling asleep or waking up frequently. Exercise can improve sleep quality, which then helps with fatigue, mood, and pain tolerance.

Stress Management

PMS symptoms are worse when you’re stressed. Exercise helps regulate your stress response by managing cortisol levels and activating your parasympathetic nervous system (the “rest and digest” mode).

Reduces Bloating

Movement and exercise can help with fluid retention and improve digestion, both of which can reduce that horrible bloated feeling.

What Type of Exercise Actually Helps?

Here’s where it gets interesting. Not all exercise is equal when it comes to PMS, and what helps depends on your specific symptoms and where you are in your cycle.

Aerobic Exercise (For Mood and Energy)

Moderate aerobic exercise – walking, jogging, cycling, swimming – has the strongest evidence for reducing PMS symptoms, particularly mood-related ones.

Research suggests that 30 minutes of moderate aerobic activity, 3-5 times per week, can significantly reduce PMS symptoms. You don’t need to be training for a marathon – a brisk walk genuinely helps.

Best for: Mood swings, anxiety, depression, sleep problems

What to do:

• 30-45 minutes of walking, jogging, or cycling
• Swimming (also brilliant for bloating and feeling heavy)
• Dancing (if you can be bothered)
• Anything that gets your heart rate up but doesn’t completely exhaust you

Strength Training (For Everything, Really)

Resistance training can help with PMS by:

• Improving insulin sensitivity (helps with cravings and mood)
• Boosting endorphins
• Improving body image and confidence
• Giving you something to focus on other than how rubbish you feel

Some women find that lifting heavy things when they’re premenstrual is incredibly satisfying. There’s something cathartic about it.

Best for: Mood, cravings, feeling strong when you feel crap

What to do:

• 2-3 strength sessions per week
• Can be bodyweight, dumbbells, or gym equipment
• Focus on compound movements
• Adjust weight based on how you feel

Yoga and Stretching (For Cramps and Tension)

Yoga, particularly gentle or restorative styles, can be brilliant for PMS. It helps with:

• Physical tension and cramping
• Stress and anxiety
• Bloating
• Sleep problems

Certain poses are particularly helpful for PMS symptoms, especially those that gently compress or open the abdomen and pelvis.

Best for: Cramps, bloating, anxiety, sleep issues

Helpful poses:

• Child’s pose (opens lower back)
• Cat-cow (gentle movement for cramps)
• Legs up the wall (reduces bloating and calms nervous system)
• Reclining bound angle pose (opens pelvis)
• Forward folds (calming)

What to do:

• 20-30 minutes of gentle yoga
• Focus on breathing and relaxation
• Don’t push yourself into uncomfortable positions

Walking (The Underrated Hero, Again)

Never underestimate a good walk. It’s low-impact, you can do it even when you feel rubbish, and it genuinely helps with mood, bloating, and cramps.

A walk after meals can also help with blood sugar management, which reduces cravings and energy crashes.

Best for: Everything, honestly

What to do:

• Aim for 20-30 minutes
• Outside if possible (daylight helps mood)
• Can be gentle or brisk, depending on energy
• Perfect for when you need movement but can’t face the gym

What Doesn’t Help (Or Makes Things Worse)

Intense HIIT When You’re Exhausted

High-intensity interval training can be great at other times of your cycle, but when you’re premenstrual and already stressed, it might make symptoms worse.

HIIT is taxing on your body and increases cortisol. If you’re already dealing with PMS stress, adding more stress through intense exercise can backfire. You might feel more irritable, sleep worse, and be even more exhausted.

The verdict: Save intense workouts for when you’re feeling better. Listen to your body.

Forcing Yourself to Exercise When You’re in Agony

There’s a difference between “I don’t feel like exercising” and “I’m in severe pain.” If you’re doubled over with cramps, vomiting from migraines, or so exhausted you can barely function, rest is the right choice.

Gentle movement might help, but pushing through severe symptoms won’t make you a hero – it’ll just make you more miserable.

The verdict: Some days, rest is the right form of self-care. Don’t let anyone tell you otherwise.

Exercising on an Empty Stomach

When you’re premenstrual, your body needs more energy and your blood sugar is less stable. Training fasted can make you feel dizzy, irritable, and exhausted.

The verdict: Have something to eat before exercising, even if it’s just a banana or a piece of toast.

A Week of PMS-Friendly Exercise

Here’s what a realistic week might look like when you’re dealing with PMS:

Monday (First signs of PMS): 30-minute walk or light jog

Tuesday: Strength training with moderate weights (30-40 minutes)

Wednesday: Gentle yoga or stretching (20-30 minutes)

Thursday: Rest day or easy walk

Friday (Symptoms getting worse): 20-minute walk, then gentle stretching

Saturday: Restorative yoga or complete rest

Sunday: Gentle walk if you feel up to it, or rest

The key is flexibility. If you wake up feeling okay, do more. If you wake up feeling terrible, do less or rest completely.

When to Exercise During Your Cycle

If you want to be strategic about when you exercise:

Follicular phase (after your period): This is when you’ll feel strongest and have the most energy. Push harder during this time.

Ovulation (mid-cycle): Peak energy and strength. Great time for intense workouts or personal bests.

Luteal phase (before your period): Dial it back. Focus on moderate intensity, lots of walking, and gentle movement. This is PMS time.

Menstrual phase (during your period): Depends on symptoms. Some women feel fine, others need to take it very easy.

By working with your cycle rather than against it, you might find exercise feels easier and more beneficial.

Other Things That Help PMS (Along With Exercise)

Exercise works best as part of a bigger approach to managing PMS:

Nutrition:

• Eat regular, balanced meals (don’t skip breakfast!)
• Include protein and healthy fats to stabilise blood sugar
• Reduce caffeine and alcohol in the week before your period
• Increase magnesium-rich foods (dark chocolate counts!)
• Stay hydrated

Sleep:

• Prioritise 7-9 hours
• Keep a consistent sleep schedule
• Avoid screens before bed
• Create a relaxing bedtime routine

Stress management:

• Deep breathing exercises
• Meditation or mindfulness
• Doing things you enjoy
• Setting boundaries (it’s okay to say no when you’re struggling)

Heat therapy:

• Hot water bottles for cramps
• Warm baths with Epsom salts
• Heat pads

Supplements to consider:

• Magnesium (helps with cramps, mood, and sleep)
• Vitamin B6 (may reduce PMS symptoms)
• Omega-3s (anti-inflammatory)
• Evening primrose oil (some women find it helpful)

Always check with your GP before starting new supplements, especially if you’re on other medications.

The Research: What Studies Actually Show

Several studies have looked at exercise and PMS:

A 2019 systematic review found that aerobic exercise significantly reduced PMS symptoms, particularly psychological symptoms like depression and anxiety.

Research from 2018 showed that women who engaged in regular physical activity had fewer and less severe PMS symptoms compared to inactive women.

A study on yoga specifically found that 12 weeks of yoga practice significantly reduced physical and psychological PMS symptoms.

The evidence is pretty clear: regular exercise helps. But “regular” is key here – you can’t just exercise once during PMS and expect miracles. The benefits come from consistent movement throughout your whole cycle.

When PMS Is More Than Just PMS

If your symptoms are severe enough that they significantly impact your life – missing work, cancelling plans, unable to function – you might have PMDD (premenstrual dysphoric disorder) rather than regular PMS.

PMDD affects about 5-8% of women and includes severe mood symptoms like deep depression, intense anxiety, or uncontrollable rage. It’s not “just bad PMS” – it’s a serious condition that needs proper treatment.

Signs you should see your GP:

• Symptoms are so severe you can’t function normally
• Suicidal thoughts or severe depression
• Uncontrollable anger or rage
• Panic attacks
• Symptoms don’t improve with lifestyle changes
• They’re affecting your relationships, work, or quality of life

PMDD can be treated with antidepressants, hormonal treatments, or other medications. Exercise can help alongside treatment, but it’s not a replacement for medical care when you need it.

Creating Your PMS Exercise Plan

Track your symptoms for a few months. Note:

• When PMS symptoms start (usually 1-2 weeks before your period)
• What symptoms you experience
• How severe they are
• What exercise you did and how you felt

This helps you identify patterns and figure out what works for you.

Questions to ask yourself:

• Do I feel better after exercise, even when I didn’t want to do it?
• Is there a type of exercise that consistently helps?
• Are there days when rest is genuinely better?
• Am I pushing too hard during PMS time?

Everyone’s different. Some women can maintain their normal routine during PMS. Others need to adjust significantly. Both are fine – do what works for you.

The Honest Truth

Can exercise help with PMS? Yes, genuinely. The research backs it up, and many women find it makes a real difference.

But it’s not a miracle cure, and it won’t work for everyone. Some months it’ll help loads, other months less so. And there will be days when the best thing you can do is rest, eat chocolate, and watch Netflix.

The key is consistency throughout your cycle rather than trying to be a hero during PMS. Regular movement all month long sets you up better than attempting intense workouts when you feel rubbish.

Be kind to yourself. If you manage a 10-minute walk when you’re dealing with terrible PMS, that’s brilliant. If you do nothing and just survive the day, that’s also fine. You’re not failing at life because your hormones are making you feel crap.

Exercise is a tool that can help, but it’s not the only tool. Combine it with good sleep, decent nutrition, stress management, and proper medical care when needed.

And remember: PMS is temporary. You’ll feel human again soon, I promise.

Now if you’ll excuse me, I’m off to eat crisps and contemplate whether I can face going for a walk. The struggle is real. Take care! x
