Who said you can’t fall in love with the gym? 😘

6 months apart and almost 2 stone down… but the best part? It’s not just the physical changes — it’s the mindset, the confidence, and the energy that’s grown along the way. 💪✨

We’re not letting the scales tell the whole story.
How Lou feels, moves, and shows up for herself matters so much more.

Here’s what’s on the rise:
⬆️ Energy levels
⬆️ Protein intake (120g a day!)
⬆️ Daily steps & general movement
⬆️ Mood and motivation
⬆️ Hydration levels

For someone still learning to love exercise — you are absolutely smashing it, Lou. I couldn’t be more proud of how far you’ve come and the changes you’ve made. 🥹❤️

Do we still have things to work on? Of course. Do we always agree? Not quite. But that’s what makes it real — it’s a journey, not perfection. 🥰

⸻

You have done incredible and again, proud doesn’t cut it. Your commitment is outstanding and even the days your struggling and don’t want to be there… you show up 💪🏽

The journey continues…. On to our next big win 🤗❤️

Lots of love K ❤️

What we spend our day like when we have a 2 second window in between clients 😂 wondering what silly stuff we can try next 😍

The real reason for this, I seen an 80 year old woman doing it and thought can’t be that hard 🤯😂! And I was confident telling Megan last night I could do it 😂

I’ll master 10 of these no bother by the end of the day 💪🏽💪🏽✊🏽

This is your reminder not to let the weekend ruin your hard work!!

Often after a long hard week you feel the need to “treat” or “reward” yourself.

Don’t over indulge, be smart and stay on track! Your goal doesn’t change just because it’s the weekend

Happy bank holiday ❤️

✨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 ✨

See you tomorrow or over the weekend and then we are back to normal next week ❤️
