You've heard that giving birth is like a marathon right?  It is actually more like 5-6 marathons!  Birth is a very physically and emotionally demanding event and just like we would train for a marathon....we need to train for birth! 
Using the principle of specificity, this unique challenge will build your mind and body so you can birth powerfully and with confidence!
It can be done at any point in pregnancy and the sooner you start, the longer you have to train. Remember, you are training for the marathon of birth, and like a marathon, you will benefit from months of preparation.
A new challenge begins the second Tuesday of every month but you can register anytime and enjoy the pre-challenge content in the app.

You deserve birth confidence and it all starts with getting fit for labor & motherhood!

Click to hear what one woman had to say about her experience with the 28 day challenge!⤵


This 28 day challenge will connect you to your core and pelvic floor so you can finally get clarity on the elusive kegel (which you've probably been told to do now that you are pregnant right?)

I will teach you how to activate your pelvic floor appropriately and then add it to movement (because regular kegels are boring!) The movements are chosen intentionally to mimic the most optimal birth positions as well as the movements of motherhood - it is  the principle of specificity at its best!

We are training for birth so you will NOT be doing hundreds of kegels every day but rather exercise that involves the pelvic floor and teaches you how to contract but also how to relax.

This app-based challenge will give you daily reminders, a list of labor/motherhood specific training exercises to complete each day and points for doing the work! (Points you can redeem for bonus content!)

You will be working to maintain your core function, to increase suppleness in your pelvis, and to feel strong and powerful!

This challenge is easy to fit into your day and effective. It only requires a couple of things....a tennis ball, a stability ball (55 or 65cm) a small towel and a resistance band.  You can make do without them but it is more fun with them....and you will use them after the challenge too!

The 28 day challenge can be done anytime in the 2nd or 3rd trimester.  Many do it once and then do it again!
There is an introduction week, 2 work weeks and then the final week is about tapering off before 'race day'. (Sidebar....birth is like a marathon but is NOT a race.)
There is a heavy focus on the pelvic floor and abdominal wall because let's face it, they face some of the biggest changes in pregnancy and birth.
Join Now for the next Challenge! A new one begins the 2nd Tuesday of every month!

Women Are LOVING The BIRTH LIKE A BOSS Challenge

Placeholder Image

Hey Kim,

I had what I call the ''birth of my dreams''.  I felt calm, prepared and in control to bring her into the world.  The staff supported me in all my decisions including labouring in four point kneel or modified four point kneel.  I gave birth in right side lying position, with my upper leg supported in abduction and slight internal rotation.   I also took more time to create an environment for us...dim lights, calming music, meditation and listening to and expressing my needs. 
Now for rest and retraining exercises...I am doing your Kegel Mojo program and love the hypopressive techniques!
Thank you so much again Kim!

I took the challenge and I am now 6 months postpartum, I thought I'd just let you know how useful I found this program. I had no complications throughout pregnancy, birth or postpartum. That includes no low back pain, no tearing and no diastasis or prolapse. I saw a pelvic health physio last week for the first time and was told I have no issues and have completely recovered.
So thank you very very much!
I've included a before and after belly shot because I was shocked at how quickly my pregnant belly shrank. The first shot is the day before I gave birth, the second shot is 2 days postpartum.
Thanks again,

I took the challenge to get me doing something every day that was safe for my body and preparing me for my upcoming birth. As a first time mom, it's not easy to know what I should be feeling or how to move in a physiologically correct way with my new shape. The challenge has taught me so much about the pelvic floor and how to release for birth, all in an easy, varied format of just about a half-hour per day.

I now feel more prepared for my birth and know that I can reuse some of the positions during labor, and keep doing them until the big day! I'd read Kim's book but this format was better for developing a daily habit and learning some new exercises. The focus on the breathing also made it a relaxing activity at the end of the day and helped ease all those 8th months pregnant discomforts.

Thanks Kim!
