    “Hey Kirstyn
    Just wanted to say a huge thank you. So far I’m at week 4, I’ve noticed a huge difference in my strength as well as doing the detox. Can’t wait to get to week 10 and see what the transformation is. I really appreciate how thorough you are in your videos. 
    Thanks again and looking forward to doing these exercises as part of my maintenance and ongoing fitness.”

    I am so excited to have completed the Core Restore programme – stronger, safer, tummy split healed and pelvic floor finally working properly and now I know how to exercise safely again. Reached a milestone yesterday where I was at a bbq for 4 hours, had a couple of drinks, didn’t have to pee the whole time, and even coming home was no longer an embarrassing rush. Such a difference in 5 weeks!!

These caused my Tummy Separation and
weakened my Pelvic Floor

After having Micaela, I returned to the same exercises I’d always done. As I felt fitter and stronger, I pushed harder and harder – it felt great! Until, I felt a large dip down the centre of my stomach. I later found out from a Women’s Health Physio that during exercise, I’d put so much pressure on where my 6pk connect, that it had separated right down the middle, from top to bottom. I was heart broken, though it answered why my lower back had been feeling less stable, and why I had developed a pooch.

After injuring my core through ‘conventional’ exercise (like the ones above), I took time out to learn how to understand, listen to and exercise my body right!

My personal experience and journey is what drives me to help other mums from going through what I have (separating my tummy from top to bottom when my daughter was 7 years old) and educating women in a very lacking field dominated by men.

Unlike generic core programs, KC Fit Core Restore was specially designed for a mums unique body

“Women are not small men, so need to exercise differently.”

I’ve helped hundreds of mum’s to dramatically improve their core strength, stability, confidence and tummy separation with the exercises and knowledge I’m sharing with you in these 6 Core focused workout videos.

As you know, I separated my core right down the middle and weakened my pelvic floor doing ‘conventional’ core exercises.

It turns out – Until your deep core is strong enough and your 2 finger plus gap is improved, we need to avoid:

  • Full prone exercises (face down)
  • Exercises where you shoulders leave the ground
  • Exercises with twisting on the core
  • Exercises with both feet off the ground
  • Exercises & movements that cause doming/ peeking

“Just like with running and a sprained ankle, you don’t have to stop doing the exercise you love forever.”

If you; allow time for your body to heal, learn how to exercise your deep core well, increase your whole core strength and endurance through these workouts – this helps you to confidently return to the exercises you enjoy.

All of this – because ultimately I want you to be able to:

  • Proudly embrace your beautiful mum body

  • Feel strong in your core function and movement

  • Understand how to confidently exercise right for your body

  • Have healed any injury, loosened any stiffness, strengthened any weakness

Basically OWN IT!!!

My story…

Hi, I'm Kirstyn Campbell the Founder of KC Fit and KC Fit @ HOME

I’m mum of 2 adorable kids, wife to one cheeky husband, and I’m darn driven and passionate about training women safely & effectively for their body. Teaching mum’s how to repair their body to get as fit and strong as they’d like with strong core foundations. 

After injuring my core through exercise, I re trained to specialize in pre and postnatal exercise and women’s pelvic floor health and haven’t stopped to stay current. I have confidently coached mums on how to exercise with your deep core – kicking their butt safely and effectively since 2016.

Some of my qualifications are: Exercise Level 3 & 4, Safe Return to Exercise (pre & postnatal exercise). Modern Pregnancy Exercise, 6 Step Restore you Core and Pelvic Floor, Pelvic Floor Focus Continence NZ, Pre and Post Natal Exercise.

I’m REPS registered (NZ Register of Exercise Professionals), being part of a body that I’m accountable to is important to me

“Society expects us women to have children. Then when we do, our bodies are expected to look and function as though we haven’t.”

I’m interested in empowering mums to learn how to love themselves from the inside out, to show them their self-worth in the season of life they’re in. To enjoy the quality of life they’d like, without the embarrassment of leaking or a pooch. To be the best version of themselves, not comparing or trying to match-up up to the pressures, false images and expectations in social media.

I’m driven to remove the shame of a mum’s body, rather encourage them to wear their mum badges with pride. Enabling them to be healthy, happy and confident in their own skin. The strongest and fittest they’ve ever been, enjoying the quality of life they deserve – with, of course – leak free laughter!
