    What is CustomFit?

    The cutting edge CustomFit app has been designed by Fitness First’s own experts to help you to develop your motivation to get fit. It features over 800 exercises (with video content) and a Fitness Logic™ system, which will get to know your preferences and deliver a set of inspiring personalised workouts to your phone.
    You will be able to track, analyse and share your progress, while comparing your Personal Bests (PB’s) with other like-minded  people via leaderboards – anytime, anywhere. The experience is designed to support beginners – educating them so that they quickly feel like experts - and in the process motivate them to build a lifelong fitness habit. No other app has been built around the science of motivation like CustomFit.

    What was our motivation for creating CustomFit?

    As the fitness leaders, we want to support people and members inside and outside the gym to go further in life. Although our gyms are suited to beginners and experts alike, we know that convenience plays a huge part in people going to a gym. The CustomFit app supports people to make positive healthy decisions and in turn, develops intrinsic motivation. We know that in today’s busy life there is not always a convenient gym available but we know that most people have a phone on them. So we see CustomFit as a solution to keeping people fit for life.

    What are the benefits of using CustomFit?

    CustomFit is a great tool to help you make the most of your training, from the workouts that suggest what exercises to do, to a library of video demonstrations. So whether you’re still finding your feet or perfecting your technique, you’ll have expert advice at your fingertips as well as from our teams in clubs who are ready to answer any questions you may have.

    Your CustomFit app will also include a personalised dashboard where you can track your progress to ensure that each and every visit is worthwhile.

    Can I use CustomFit outside the gym?

    Yes, getting some fresh air is a great idea when you are exercising, so CustomFit has been designed to track every walk, run, or cycle so you get a full picture of your training whether in the club or outside the club.

    How much does it cost?

    CustomFit is free for everyone to download.

    How can I access it?

    CustomFit can be downloaded from the Apple App Store and Google Play store.
