To legally train clients on a one-to-one basis in the UK, you must hold a Level 3 Personal Trainer qualification; a Level 2 Gym Instructor certificate alone isn’t enough.
If you’re planning to start a career as a Personal Trainer in the UK, you’ll come across two main qualifications: Level 2 Gym Instructor and Level 3 Personal Trainer. Below, we explain the difference between the two qualifications, and what you can do with both. (Estimated read time ~3 minutes.)
