There are around 60000 qualified gym instructors and personal trainers in the UK alone, with several thousand more qualifying each year. The Register of Exercise Professionals' (REPs) Level 3 qualification is seen as the principal goal for all instructors, and a key part of this is advanced circuit training.

«Fitness Professionals. Advanced Circuit Training» is the advanced companion to the definitive «Fitness Professionals: Circuit Training». Building on the basics of the first book, this new title is the only book in the market that specifically deals with more complex and innovative circuit methods — including kettlebell exercises, boxercise and increasingly popular 'boot camp' military-style exercise — and which actively helps trainers in the industry achieve their professional qualifications.

Using step-by-step guidance to planning and coordinating sessions and illustrated by quality photographs, «Advanced Circuit Training» is written in accordance with REPs national standards for Level 3.
