At Sleven, we aim to help each of our members to develop their strength and fitness to meet their own personal objectives and to do so within a supportive and friendly environment. We are committed to providing our members with the best possible coaching and to help achieve this, we have developed Coaches Ed., a rigorous 4 month education programme. We are passionate about encouraging and enabling athletes to progress to become coaches if that is their ambition and our Coaches Ed. programme is an ideal place to begin to develop the tools to become a leader in our community. Coaches Ed. covers a wide variety of topics including:
  • A 6 week intensive practical course teaching you the main exercises we do at Sleven and how to effectively cue, scale and progress them.
  • An optional structured shadowing programme with an assigned mentor to help you take your first steps on the route to coaching.
  • Theoretical aspects around health and fitness and how the body adapts to exercise.
  • How to programme workouts individually and for a class based environment.
  • A crash-course in nutrition.

My vision for Sleven was to create a home away from home for our members. Through a shared goal, fitness, we have brought people together from all over the world of different age groups and backgrounds, creating a diverse and supportive community that will instantly become your family.


I believe that fitness is for everyone, regardless of age or fitness background and that to be sustainable, it must be fun and enjoyable. We pride ourselves on providing an environment in which all can feel comfortable in pursuing their fitness goal, whether that goal is to be a bit fitter or to be a competitive athlete.
