Fitness instructor

Job Description

Self-employed | Competitive Pay


We’re looking for motivated, experienced fitness professionals to join The Infinity Studio Essex, the home of functional fitness in Southend-on-Sea. This role is ideal for instructors who already have an established client base in Essex and want a premium space to coach from while being part of an energising, community-led studio.


About the Role

This is an on-site, self-employed position based in Southend-on-Sea, Essex. Applicants must already be living in the UK and within a commutable distance of Southend-on-Sea, Essex, as the role may require early start times (as early as 5:30am). Unfortunately, we are unable to consider applications from candidates based outside the UK.


We’re initially looking for someone who can commit to teaching our functional fitness classes on Monday evenings and Wednesday mornings. There will be a small number of class shifts each week to begin with, with the potential for this to grow.


Key Responsibilities

1. Deliver high‑quality, motivating functional fitness classes.
2. Set up and prepare the studio for functional sessions.
3. Engage confidently with members before, during and after sessions to build an inclusive, upbeat training environment.
