Attention all mums!

Watch this short video and discover how I healed my core after 4 kids! 👇

I am Renata Sanko, a fitness trainer and a mum of four kids.

I have given birth 4 times in under 8 years, and I gained over 50 kg (110 lbs) during my pregnancies.

Before I decided to change my life and live a healthier and fulfilling life I struggled really bad.

After my pregnancies, I faced horrible symptoms like leaking urine when jumping or sneezing. I even had to wear pads to get out of the house 🙈, I had severe back pain and mummy pouch that just wouldn’t go away.

My postpartum period was real torture.

I had a demanding baby, our breastfeeding journey was extremely challenging and I developed postnatal anxiety. Something, that apparently is not so much talked about.

I was living a real nightmare.

I was afraid for my kids, for myself... I was afraid of everything.

I gained weight, my symptoms were becoming worse and I felt massive mum guilt every time I said my kids I can’t play with them, run or jump on the trampoline.

I learned how to make excuses for my symptoms that were preventing me from being the mother I wanted to be...and the wife I once used to be.

I had 4 fingers wide Diastasis Recti  and a huge mummy tummy and I was wearing pregnancy clothes.

I was wearing pads because I was afraid I would pee my pants in public.

I lied to my kids I can’t jump on the trampoline because I would pee myself every time I jump.

But one day I touched the ground when a friend of mine asked me if I'm expecting again...

It hit me so hard!

I knew I had to do something to change my life and to become the person I once was...

I started learning, researching and I made a decision to finally take my life in my own hands...

I soon realised that all of my symptoms were caused by a weak core and pelvic floor muscles and a 4-fingers-wide Diastasis Recti.

*Results vary depending on starting point, goals, and effort.

*Results vary depending on starting point, goals, and effort.

And then, in less than a year I:

  • Closed my Diastasis Recti to functional 1 finger width
  • Lost over 20 kg and finally got abs!
  • Improved my pelvic floor function and stopped leaking urine once and for all
  • Started lifting weights and doing high-intensity exercises I never dreamed I would

So, what am I talking about?

After years of research, I learned four things why mums can’t get rid off the mummy pouch and can’t heal their core and pelvic floor...

Mummy pouch is often caused by Diastasis Recti or abdominal separation.

This is widening of a gap in your abdominal muscles and it is happening at Linea Alba, the connective tissue in the middle of the abdomen. The tissue is widening and stretching and losing its elasticity.

Many mums want to lose weight after birth and start with rigorous exercises that will actually make their condition worse!

Many exercises like crunches and sit-ups should be avoided when dealing with abdominal separation. By doing this kind of exercises that many personal trainers and influencers recommend mums are only making their condition much worse!

Mums endure painful and embarrassing symptoms all the time!

Many mums also face  symptoms like leaking urine when sneezing and coughing, incontinence, pressure down there, backache and bad posture.

They are not enjoying sex like they used to before kids!

This is often caused by Diastasis Recti.

Doctors don’t assess mothers for pelvic issues or Diastasis Recti

Many mums don’t know there is a solution because no one told them! They don't have to endure these symptoms.

It is never late to start healing!

And in case you were wondering, this FREE 14-day Core Recovery Challenge is perfect for all:

  • new mums
  • mums that have multiple kids
  • mums that have grown up kids
  • mums that are expecting

Actually, every woman could benefit from this FREE Challenge.

​And in case you were wondering...


I know that there are some websites out there that offers you something really cool for free but then stick you into some program that charges your card every month.

Or they offer you only free PDF that you can’t really use properly and save the good things for paid programs.

This isn’t one of them.

There is NO hidden continuity program and you are getting full 14-day CHALLENGE with lifetime access to all the videos and educational materials.

Simple as that...

And in case you were wondering why I am doing this...

Well, there are actually a few reasons...

  • Because I was there! I couldn’t afford programs to heal my Diastasis Recti and I know how hard it can be trying to find the right information. I want for every woman to get an opportunity to heal their body properly after giving birth and do it correctly. I believe this should be done routinely and free
  • Because I want you to get my product in your hands, and when you see how awesome it is, it should get you excited to buy other products from me if you want to do so...

Time is of the essence!

Here's why...

How much time do I need for exercises each day?

The workouts are around 20 minutes long. I recommend that you do them 5 days per week, but you can also do them every day if you wish so.

What equipment do I need?

This entire challenge can be done without buying any special equipment. I do recommend to have some equipment, but you won’t be missing out if you do everything with no equipment at all. The recommended equipment is:

  • Light resistance band – you can use a pair of old tights or leggings instead. I’m using a powerbands loop, but feel free to just wrap your resistance band (or tights/leggings) around your legs if you don’t own a loop. 

Do I need a gym membership for this challenge?

No, The Core Recovery Challenge is a program you can do at home, no gym membership needed! There is limited equipment needed but you can do the challenge with no equipment at all and still get the results you want. It's all up to you now!

I gave birth 10 years ago can I still join the challenge?

Yes, it's never too late to start healing your core. The core muscles work in a similar way as any other muscle in our body. Once we learn how to contract and relax them in a right way great things can happen. I will show you that here...
