Scott & Lucy Merrilees, Core Fitness


S & L

Scott and Lucy Merrilees, both 35 years old have been working in the fitness industry for over 14 years. Between us we run lots of weekly exercise classes to suit everyone.

We offer a friendly and reliable service to anyone who is looking to get started with exercise or who is looking for a change to their current routine. Whatever goal or target you are trying to meet, we can help to motivate you and give you that extra push to get there.

Scott has been running weekly HIIT (high intensity interval training) circuit training classes in Chalfont St Peter and Amersham for over eleven years. The classes are very friendly (no military style) and can be worked at your own pace. Don’t let the word ‘high intense’ or ‘circuit training’ put you off. All levels of fitness are welcome and exercises are always adapted to suit your needs. It’s a great way to exercise! 

Together we run small group personal training sessions with a maximum number of 8 people per session. All group sessions are programme specific using specific equipment you may see in a fitness gym. The session is a great way to learn how to exercise correctly and with perfect technique. You will feel like you have had a great workout and see the benefits of working out in a smaller group.

Scott has also been running female fitness classes in Amersham for over seven years. The session is female specific and is suitable for all ages. Mums looking to get back into exercise after child birth are welcome, anyone new to exercise or maybe you are already training regularly you will get a great workout and meet some great people. Younger children are welcome to join you with this class also.

Lucy has been running fitness Pilates in Amersham for two years. The classes are open to both males and females and the main focus is strength and flexibility. Many people come to the class with niggling injuries, stiff and tight muscles, bad posture and all see results straight away.

For all our classes you don’t need any equipment as we provide everything. All you need to do is turn up, have fun and feel great. Our classes are run indoors and outdoors depending on the weather, all in private locations.

Whatever type of training you’re looking for, whatever goals and targets you may have, Core Fitness can help.

Please take a moment to read our testimonials page (about tab) and see what some of our regular clients say about the type of classes we offer and how we have helped them achieve their goals. If you would like any further information or would like to book onto any of our classes, please don’t hesitate to get in touch.

    image1Scott’s classes are inspirational, energising, body changing but above all, fun! Every class is different. He helps each person individually so much so it feels like a private lesson. He is enthusiastic and always encouraging.

    IMG_1972Scott’s aspirational classes allow everyone, no matter what their age or ability is, to better themselves. EVERY class is different. You have no idea what you will be doing one class to the next. It never gets boring!

  • Paul James

    pjj Every session is different which keeps up my interest and every session is good fun although I can definitely feel that I have done a work out at the end (and the next day!) 

  • Julie Van Den Bergh

    jvdbThe classes are HIIT style, but there is no pressure to go at full pace, you can go at your own pace and choose weights to suit you. It’s like Chalfont St. Peter’s answer to the Body Coach! 😉 Give it a go!

    image2Scott has personally helped me feel much stronger again and to reach my goal of building up my fitness again after pregnancy. I would highly recommend mum & baby fitness- thank you so much Scott!
