I recently asked some of my lovely members to give me three words to describe how they felt before they joined our classes

FAT, FED UP & FRUMPY were amazingly the top three responses.

My next question was “What stopped you from joining a class before?” the answer really shocked me. For most it was the thought of walking into a room full of Lycra Clag, teenage, stick insects all bouncing around looking perfect.

Well I can promise you, when you come to Slim and Shape Up  you will find a warm welcome and real women, we all have the same hang ups and we all want the same thing, to be a little bit leaner and to get a little bit thinner, but (and it’s a BIG BUT) we all want to have a good laugh while we do it. So, you will find fabulous music, easy to follow routines and no pressure to be perfect. You will also meet some of the nicest people ever.

My name is Mary Ramsden and I have been running my fitness classes in the Lincolnshire area since the millennium year 2000. My passion is to make exercise fun and uplifting whilst helping people to get fitter, healthier and lose weight. Our classes are for everyone!

Just like everyone I have a story…. you can read all about me, my passions and experiences  by clicking here

I ‘d love to meet you at Slim and Shape Up.
