That stubborn belly bulge?

You might think it’s just baby weight — but no matter how much you train OR diet, it’s still there.


Turns out, it’s probably ab separation — also called diastasi
s recti. Over 60% of mums have it, but most don’t even know.


That’s why my program includes ab-separation and pelvic floor recovery exercises built right in:


  • How to safely check for ab separation
  • The exact exercises that repair and rebuild your core (without making it worse)
  • What movements and workouts to avoid while you heal
  • Step-by-step support so you never feel like you’re guessing


Stop guessing. Start repairing.

Join today and start healing your core from the inside out.

Client Testimonials

Kirsty

Can I just say how much I like the period tracker. I have never ever tracked it! Like ever! Even when trying to fall pregnant. I obviously knew when I was on the pill 5 years ago. And it's spot on too.


Noticing a big change in the way my clothes fit and how I'm feeling in just 4 weeks. Feeling much stronger, building muscle and not relying on caffeine to get me through the day.

I'm actually looking forward to my workouts and meals each day.

It's definitely retrained the mindset for the better.


So a huge thank you for creating an app that makes me accountable.

Nicchia

This app... IS FREAKING AWESOME!

Love the swap options for both the food and the gym.

I absolutely love that if I can't make the gym then I can change it to home workout/movements instead.

You have put so much thought into this app, Mariah. You can tell it has come from someone who has walked the walk and knows what would be so helpful!


Well done, beautiful!

Miranda

I feel different. I feel 'shredded' like I've left the old behind. I saw the meal plan today and workout plan.

Mariah, you've outdone yourself with this app!

Steph

I haven't got time to go to the gym this arvo so a quick 30mins workout at home it is. Love the app so much that I can turn gym experience with limited stuff at home.

Jo

Just wanted to give a shout out to Mariah for providing this amazing app!

4 weeks down and I'm seeing great results. Thank you Mariah for the last 4 years of my journey, you have always been in my corner.

Emily C

I'm feeling so amazing! I'm loving my program so much. Thank you for all of your support.

​​Seeing those side by sides omg I'm so shocked. I didn't think I could feel a big difference but seeing that is just insane.

Rochelle

I am so happy, can really start to see it working now and I have dropped to 91.8kg overnight. Which means I have now lost 5kgs in 4 weeks. Best thing I have ever done!


Couldn't have done any of this without your amazing knowledge and constant support.


I feel like my big goal of 70kg or less is actually achievable now! I don't crave chocolate or anything anymore. Feel very content with food.

Kaya

​​I cannot thank you enough for these last few months. They have been both incredibly hard yet rewarding. I have found it hard to love myself from within since becoming a mother. I wanted to thank you for helping me in the process of changing my mindset and the relationship I have with food and gym. I am on the best journey to loving myself again because of you and your constant support and love.

Anna

I've never had such a supportive, motivating and of course knowledgeable community to thrive in I'm absolutely sticking around. You guys have radically changed my life - I don't even have words.

Annys

​​Having a coach support you the way Mariah has and continues to do, fuel's the fire inside to keep going. She teaches me the tools to overcome the challenges I've faced emotionally, physically, and with my self-belief. I now know I am capable, that I can keep myself accountable to my choices and actions. I am confident, strong, inspiring, disciplined and focused. I am independent and self-sufficient and ready to step into everything I'm working hard for. I'm a thriving mumma! I am beyond grateful for you, Mariah

Chels W

Permanently 10kg down a whole lot better at looking after myself, can't thank you enough.​​


So unbelievably grateful for you, stood on the scales 69.70. Under 70 for the first time since being pregnant. I just want to thank you for everything you’ve done, I am finally in a tiny bikini and smiling! And love my body for what I’ve got and how strong I’m getting. You have no idea how much you’ve changed my life in such a short time. So much love.

Luana

​​I’m just so amazed I’m allowed to eat all this food and lose weight too. Like I'm thinking to myself why have l not done this sooner. I've been leaving on tuna salad and shakes and got no results.

Michelle

I've come to terms of why I was always under eating. It's hard work making food especially with two little crawling on your leg/crying. But seriously, Mariah, you've made it much easier!

Cassy

I'm feeling so much better when I wake up, it's not like I'm dragging myself out of bed. I almost bounce up and I'm good!


Sleeping so much better!

Jane

​​You changed my life so positively and for this you will ALWAYS be such an integral part of my success. I am forgetful and by all means the imperfect client but you've embraced my quirks and loved me all the while. So thank you a million times for everything, you cannot even begin to comprehend your guidance, you are a superstar coach and an even better human. THANK YOU, THANK YOU, THANK YOU for the past 2 years of coaching. It has been so much fun and hard work and reward.

Kaya

​​​​Mariah, you're an amazing coach and person! I appreciate you so much! Forever grateful for you! I've been up and down these last few months, but you've been there to prep talk me every time. I've still got a long journey ahead but I couldn't have done this without you. So much love for you as my coach.

Jess R

​​I will be sure to check in and let you know how I am going and reach out if I'm struggling. I appreciate how supportive you are I have never felt so safe and able to be raw and real as I do coaching with you in such a short time! Thank you again.

Kayla

​​​​​​I’m feeling so much stronger again, amazing what food can do haha. I went shopping and got new clothes on Monday (by myself - no children) just some me time! And I bought size 6 and 8!! Sometimes 8s were even big on me! What the actual f? So safe to say I’m loving myself sick. Totally obsessed!

Sam w

​​8kg down, over 20cm lost! Movement has improved greatly - even with chronic injuries. Thank you Mariah!! Without the support and encouragement of Mariah and the people in the MJ FIT community, I would not have held myself accountable nor would I have kept pushing through adversity. Choose what you want your time passing to look and feel like for you!

Jess

I'm so proud! I'm actually in the gym now doing a workout. You are amazing and supportive. Thank you!

Tayla

​​This is why I chose your program! Understanding that being a mum solo for 4 weeks at a time while hubby is away at work, a sick baby feeling unwell yourself, endless duties to do yes going to the gym would be great but sometimes it's just not possible that day but giving your clients the education on nutrition and how important rest is, is like no other!!!

Nikki

Another non-scale victory! From years of undereating to now fueling my body. My skin is glowing! I have life in my face again.

Isabella

​​A massive thank you to Mariah! Without your support and positive encouragement, I wouldn't have achieved what I did. You have passed on so much knowledge about food and how to train properly to get results. I can't thank you enough. I'm walking away a healthier, ​​fitter and confident person.

Abby

​​​​From day one of my journey with Mariah it's been amazing! Not only is she my coach but she's become one of my very best friends and has been by my side through so much! I'm forever grateful for the day I was introduced to this beautiful lady! Love you lots girlfriend, your passion and care for all your clients doesn't go unnoticed you're truly an incredible human and an inspiration!

Georgia

I'm so grateful to you for helping me through this process Mariah and although it's been shit I've learned a lot and so glad I picked you as my coach.
