✨Something real special here ✨

Can you spot the MASSIVE difference in this picture 😍

Let me tell you… so, aesthetically the difference is unbelievable no doubt on that. As well as;

4 stone ⬇️
4 dress sizes ⬇️
Energy levels 💥⬆️
Mobility and movement ⬆️
Overall health ⬆️

These are just some of the ongoing benefits. As well being able to do things with the kids she hadn’t done in a long time or never thought was possible again!

That’s not the main difference….

LOOK AT THAT SMILE IN THE SECOND PICTURE ❗️

That’s the face of someone who is no longer unhappy, miserable or lethargic. That is the face of someone who has shifted their mindset, doesn’t mind the camera and has energy in abundance to run around with her young kids.

You being happy and healthy was my number 1 goal, I knew everything else would fall into place as soon as we nailed that.

I couldn’t be prouder of your progress from start to finish, your commitment, dedication and constant hard work.

We aren’t finished yet but 4 weeks to holiday for you to enjoy some down time and a more active, healthy holiday ❣️

Forever proud of you maryanne0109

Just a gentle remind for everyone……. I am back in the gym tomorrow!

It’s been amazing to spend so much time with my nieces, nephews and family but I am well rested and ready for the rest of the year ✨

The body of someone who is 4 stone down 💃‼️

I am incredibly proud of you. I known this was hard to fit in between family life, working life, all of the kids events and everything in between but we/you done it ❤️ you haven’t come up with any excuses not to make it happen, the opposite actually, created time, squeezed it in and just made it happen!

You made the time for you, committed to the journey, the process and here we are… 4 stone down since Feb!
