Period Power

How to work out during your cycle? 

Ever notice how some days you feel like you can absolutely crush your workout? And, other days, not so much What’s the deal?

It has a lot to do with your menstrual cycle, and when you understand how it works, you can use it to your advantage

That’s right Your period is no longer an excuse It’s a super power!

Harnessing your hormones

How you feel and how your body reacts to activity all comes down to hormones How much pain you feel, how fast it takes you to recover and your ability to push through a tough workout are all related to hormones

But during your cycle, those pesky hormones are always changing, so the key is to understand your cycle and harness the power of each phase for your fitness goals

The bad news is that there’s no magic workout schedule that will work for everyone We’re all different In fact, specialists are only starting to understand the very different exercise needs between men and women Did you know that women were once thought of as mini men?! Yes, we laughed too, but the fact is that our bodies really do work differently than a man’s

Now it’s time to use this to our advantage Wuu huu!


A perfect match

Dr. Stacy Sims, a world leading expert in female physiology and endurance training discovered how to match workouts to the different phases of your cycle to get the best result

Here are two reasons to follow her magic formula:

1. You deal with stress better

    You probably know when your premenstrual phase is, right? Well, be careful not to exercise too hard in this phase because when you do, you produce too much cortisol, your body’s stress hormone To do this, your clever body “steals” estrogen and progesterone which causes hormones to be a bit out of whack The result? You’re likely to have less power and recover more slowly

    Don’t forget to pay attention to what you eat too! Too little food can cause stress and definitely makes exercise a slog Try taking magnesium supplements that help with sports performance. These magical little tablets can help with fatigue and stress too

    2. You can reduce cravings

    In the week before your period, you actually burn calories faster than usual No, this is not an excuse to binge on your favourite snack, but you do need a little extra – about 300 extra calories per day

    You may have also noticed that you get some intense cravings the week before your period It’s those hormones at work again, which can cause your serotonin levels to drop Serotonin is the feel-good hormone that makes you feel satisfied, full and confident

    So, a little extra food can help bring your serotinin levels back into balance and help with those cravings Skip the ice cream and instead, try sweet, carbohydrate-rich whole foods like sweet potatoes, honey and dates They’re like sweets from nature and they have the added bonus of making you feel relaxed thanks to the little serotonin boost! Yum!

    Time for action

    So how do you actually match your workouts to your cycle? Here’s an example schedule we’ve created to help you get started It’s based on the four phases of your cycle: menstrual, follicular, ovulation and premenstrual

    ❣️ Menstrual phase

    The best activity when you have your period is going to be different for everyone It’s important to listen to your body and do what is right for you If you have energy during this phase, you go girl!

    Get your butt to the gym Join that cardio class or up your weights In the first half of your cycle, you actually build muscle more easily, so make the most of it!

    But, if you feel weak, don’t push it Take it easy and instead, do a yin yoga class or go for a quiet evening walk to help soothe any cramps


    ✨ Follicular phase

    This phase happens about 7-10 days after the last day of your period You might start feeling happier and more energetic and that’s because your estrogen levels are on the rise This is the perfect time to get outside more Maybe even try a new sport Rock climbing, anyone?

    During this phase, you’ll excel at things that need more power and speed Opt for cardio exercises like cycling, swimming and interval weight training and if you’re a runner, now is the time for hill repeats or sprint training


    ☀️ Ovulation phase

    Boom! This is the phase where you are at the top of your game The ovulation phase, which is the 3-4 days you are most fertile, is all about stamina and strength In this phase, you’re likely feeling more confident and social too so now might be a good time to grab a friend and go to a group exercise class Try a sweaty HIIT session a heavyweight training or power yoga


    🧘‍♀️ Luteal phase

    Time to wind down

    10-14 days after ovulation but before your period, you might be feeling a bit more tired That super woman strength and stamina you experienced in the ovulation phase will be replaced by a need to rest and recover

    You’re going to want to choose much lighter activities during this phase This could also be a good time to focus on flexibility, form and technique Swap out those high-intensity exercises for things like slow yoga, Pilates, gentle bike rides or lightweight technique strength training

    Now that you know how to match your workouts with your cycle, it’s time to go crush it!
