How to start fitness coaching in 4 steps

  1. 1
    Get qualified or start as online coach
    Level 3 PT adds credibility and opens gym doors, but isn't legally required for general online fitness coaching. Start online while studying if you want the qualification.
  2. 2
    Build social media presence
    Instagram and TikTok are where fitness clients discover coaches. Post workout content, tips, and transformation stories consistently — 3+ times per week minimum.
  3. 3
    Run a free challenge
    Offer a free 4-week challenge to build your email list and demonstrate your coaching style. Convert challenge participants to paid 1:1 coaching.
  4. 4
    Launch group programmes
    1:1 coaching has a time ceiling. Group programmes (10–30 clients, same programme) at £100–£200/person/month is the path to serious income.
