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.

I'M READY!

I’ll look after you while you’re looking after everyone else

Whether you're balancing motherhood, feeling overwhelmed or just trying to stay healthy, Mariah Jean Fit is for you.

Client Testimonials

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.

Carly

​​So beyond grateful. I mean I stuck to the plan pretty much 100% but in my mind the results are wild considering | didn't do anything DRASTIC like drop to really low calories or do intermittent fasting or workout every single day multiple times a day, so thank you for teaching me that consistent hard work breeds better results than deprivation. I'm so excited by the mindset I've adopted now!

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

​​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.

Phe

​​So I'm proud of myself for getting over my insecurities in regards to going to a commercial gym as l have always done free weights gyms and classes so all the machines were scary to me but now I feel good about it!

Tom

​​I am pleased to say that Mariah supported me, empowered me and softly but surely challenged my beliefs to help me achieve my goals and I am so grateful for her abundance of knowledge and deep level of care. I am now well on the way to achieving my initial goal, but during the process with her incredible knowledge of health, nutrition and the human body Mariah helped me understand and overcome something so much more important.

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!

Constantine

Honestly, I can't thank you enough, Mariah. This was the best investment of my life. I don't think I would’ve pushed through as much as I did without your guidance. I've also learnt so much along the way about nutrition and training. Even those hard weeks I had mentally and physically, your words just sparked motivation every time is listen to your check-in. Thank you once again.

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!!!

Hayley

​​​​I feel like with each check-in and each adjustment you make for me, it's becoming so easy to change my relationship with the right things for me. Thank you from the bottom of my heart for truly hearing me every single time.

Jess

​​l've been meal planning from Mariah's ebooks for almost a week now and the improvements and progress and benefits are just unbelievable...last time I worked with Mariah I lost 8kg in 10 weeks all while never being hungry and loving the food I was eating. You are a literal genius Mariah and I am thanking my lucky stars I'm back with the best getting back on track.

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!
