MMF has changed my whole life.
From day one, first session, Millie was so welcoming & kind. And nearly a year later of me being apart of the MMF Family she without fault always has the biggest smile and welcomes you every single day.
Mil reassures you of your strength & your ability to push yourself to be the best version of you. Making sure each session you leave feeling powerful, strong & ready for your day ahead.
Mil is amazing & I support her and what she stands for so incredibly much.

MMF has honestly changed my life for the better in so many ways. Before starting with millie I was the type of person who wouldn’t step foot into a gym purely based on the fact I would be judged, MMF is the most welcoming, loving family anyone could ask for. Millie is such a unique coach and anyone who is trained by her will say we are incredibly lucky to have someone who cares for each of us so much.
I couldn’t imagine my life with Mil & the MMF family. She has taught me to love myself in so many ways, and I don’t think I will ever be able to train anywhere else.

I was nervous to start at MMF but instantly felt welcomed and seen. Mille has created a space where the environment is positive and supportive. I love how everyone is there for the same purpose and all the girls are beyond friendly and helpful. I have seen a change in my mindset and I find myself happy and excited to go to the gym where as in the past I have struggled with motivation. Millie and Kay are super encouraging and fun to have as trainers, MMF is the best choice I could of made for myself so thank you 🤍🤍
