28 Day Slender Plan





Busy Mum looking to shed a few extra pounds, or an office go-er wanting to look your best in your smart wear? 

We've designed the ultimate 28 day plan to throw out all the guesswork that comes with weight loss and help you live healthier and achieve your goals faster, smarter, and better than ever!


The biggest struggle when it comes to weight loss isn’t learning how to do it, but rather, finding a solution that bridges the gap between an unhealthy lifestyle, and your ideal, healthier lifestyle—without depriving you of the things you love.  

That's why we created our 28 Day Slender Plan.





28-Day Slender Plan Benefits 




The 28-Day Challenge was designed to get you amazing results with little disruption to your everyday life. With that, here are some benefits you can expect if you commit to following the program and complete the full 28-days of the challenge:

  • Lose weight
  • Build muscle
  • Boost confidence
  • Get visible results
  • Create lasting, healthy habits


What Makes The 28-Day Slender Plan Unique?



“I’ve tried other workout programs and nutrition plans before but none of them worked for me. What makes this 28-day weight loss challenge different than the rest?”



Being healthy shouldn’t and doesn’t mean you have to sacrifice the things you love to achieve your weight loss goals—and that’s what the 28-Day Slender Plan is all about! It’s about creating a balance that works FOR YOU while providing simple, effective, and reasonable solutions to everyday struggles.


And when you sign up for the 28 Day Slender Plan, you won’t have to worry about getting a gym membership, or spending hours upon hours meal prepping food you probably won’t eat anyway. You’ll be given the freedom to adopt a healthier lifestyle, on your terms, but still see amazing results.

Really filling and taste like iced lattee!

I recently got the vanilla frappe and it taste just like iced latte! Mix mine with water and ice would recommend this flavour if you love iced lattee! The white chocolate protein bars are really nice as well, have like a soft brownie texture, most protein bars I've tasted are really really powderdy or rock hard!
