There is a big misconception that during your period you're meant to be resting and taking it easy, whilst actually science tells us the opposite. Understanding the relationship between exercise and your menstrual cycle can help you optimise your fitness routine and overall well-being. We will explore how different types and intensities of exercise can influence your cycle, provide tips for exercising during different phases, and highlight the benefits of staying active throughout your menstrual cycle. 

- The Menstrual Cycle Phases -

To understand how exercise affects the menstrual cycle, it’s crucial to know the different phases:

Menstrual Phase (Days 1-5)

This is when bleeding occurs. Hormone levels, particularly estrogen and progesterone, are at their lowest. To confuse things a little, this is also the first half of your follicular phase.

Follicular Phase (Days 1-13)

Begins on the first day of menstruation and lasts until ovulation. Estrogen levels start to rise, leading to increased energy and strength. The follicular phase is also known as the low hormone phase.

Ovulation (Day 14)

The release of an egg from the ovary. Estrogen peaks, and there is a surge in luteinizing hormone (LH).  Occurs around the midpoint of the cycle and lasts 24-48 hours

Luteal Phase (Days 15-28)

After ovulation, progesterone levels rise, which can cause fatigue and decreased performance for some.

Always listen to YOUR body. No two women are the same especially when it comes to our menstrual cycle. Intuition plays a huge part in this and if you feel you need to rest when you're 'supposed' to feel energised, then rest, and vice versa.  

- Menstrual Phase, Days 1 to 5 -

*first half of your follicular phase

Great time for: Power workouts. Don't be fooled by all the ads you see telling you to take it easy whilst you're on your period. During this phase energy levels are high and it's a great time lift weight and do some hight intensity training, think HIIT workouts and plyometrics You've got this. BUT, during menstruation many women experience symptoms like cramps and fatigue so it’s essential to listen to your body and rest or opt for lighter workouts if that feels appropriate for you.

- Follicular Phase, Days 6 to 13 -

*second half

Great for: Highest intensity workouts and heavy lifts. Once you've stopped menstruating you can crank it up a notch. This phase is where you can really push it, if you're doing HIIT training think about reducing your rest times, if you're incorporating sprint training into your workouts this is when to do. If you're ready for some heavier lifting then this is the perfect time of the month to do so. The rise in estrogen levels boosts energy, strength, and endurance. Many women find they can push themselves harder and recover faster during this time all the way to ovulation. 

- Ovulation, Day 14 -

Great for: Personal bests. Due to the peak in estrogen in the days leading up to ovulation, women might feel a peak in physical performance. The days leading up to ovulation are a great time for personal bests and challenging workouts, which is perfect because you've just had the opportunity to build up to this in the following phases. Again, some women may feel the opposite, and this where tracking comes in really useful to workout how YOU feel during your cycle.

- Luteal Phase, Days 15 to 28 -

After ovulation, progesterone levels rise causing many women experience fatigue and reduced performance. It’s beneficial to switch to more steady state cardio like swimming, cycling, or moderate-intensity exercises like pilates and yoga. Focus on maintaining consistency rather than intensity. Gentle exercise can also help manage PMS symptoms, including mood swings and bloating.

Here's a terrible MTB analogy to help - think of your menstrual phase like a blue trail, your feeling good, practicing jumps and hitting techy terrain, after a few days your now ready to hit some red runs (the second half of your follicular phase)  here we're going that little bit bigger, faster and pushing ourselves that bit more. After a few days on the reds, ovulation hits and boom, we are now sending on the blacks ticking off features everywhere, but this hight doesn't last long and soon we're back on the greens (luteal phase). We've had our fun and now it's time to recover before our next period, so let's stick to the green trails for some easy riding. 

- Benefits of Exercising During Your Menstrual Cycle -

Pain Relief

Regular exercise releases endorphins, which act as natural painkillers and can help reduce menstrual cramps.

Improved Mood

Physical activity increases the production of serotonin, a hormone that boosts mood and helps alleviate symptoms of PMS and menstrual-related mood swings.

Better Sleep

Regular exercise can improve sleep quality, which can be disrupted during certain phases of the menstrual cycle.

Increased Energy

Staying active helps maintain energy levels, combatting the fatigue often associated with the luteal phase.

- Tips for Exercising Throughout Your Menstrual Cycle -

Track Your Cycle

Use a menstrual cycle app or calendar to understand your phases and plan your workouts accordingly.

Stay Hydrated

Hydration is crucial, especially during menstruation and the luteal phase, to help reduce bloating and fatigue.

Listen to Your Body

Adjust your workout intensity based on how you feel. It’s okay to rest or opt for lighter activities if needed. 

Nutrition

Eating a balanced diet rich in iron, magnesium, and healthy fats can help mitigate some menstrual symptoms and support overall performance. Blood sugar levels can be more unstable during the luteal phase , resulting in cravings and mood changes. Opt for meals and snacks that contain complex carbs and protein.

Warm-Up and Cool Down

Proper warm-up and cool-down exercises can prevent injury and reduce muscle soreness. Especially during the follicular phase; whilst during this low hormone phase we a primed for high intensity exercise, increases in inflammation (due to higher levels of estrogen) during this phase may mean it takes longer to recover from workouts, so focusing on recovery is key. 

Exercise and the menstrual cycle are interconnected, and understanding this relationship can help you make the most of your workouts while managing menstrual symptoms. By tailoring your fitness routine to the different phases of your cycle, you can optimise your physical performance, enhance your well-being, and maintain a healthy, active lifestyle. Remember, every woman’s body is different, so it’s important to find what works best for you and to listen to your body’s signals. Stay active, stay informed, and embrace the positive impact of exercise on your menstrual health.
