The Level 3 Personal Trainer Course is structured to take you from foundational knowledge through to professional practice. Each unit builds on the last, giving you both the theoretical grounding and practical skills required to design, deliver, and evaluate effective personal training programmes.
Below is an overview of what you will cover throughout the course.
Unit 1 — Anatomy, Physiology & Nutrition
A solid understanding of how the human body works is the foundation of effective personal training. In this unit, you will study musculoskeletal anatomy, the cardiovascular and respiratory systems, and the role of macronutrients and micronutrients in health and performance. This knowledge directly informs how you design sessions, prevent injury, and advise clients on fuelling their training — making it one of the most practically relevant modules of the course.
Unit 2 — Health, Wellbeing & Lifestyle
Personal trainers work with clients across a wide range of starting points and health backgrounds. This unit equips you to carry out professional client assessments and fitness consultations, identifying goals, lifestyle factors, and any contraindications that should inform programme design. You will learn how to support clients holistically — addressing not just physical fitness but sleep, stress, and general wellbeing — which is increasingly valued by clients and employers alike.
Unit 3 — Programming & Periodisation
The ability to design structured, progressive training programmes is at the heart of what separates a good personal trainer from a great one. This unit covers personal training programme design principles including goal-setting frameworks, resistance and cardiovascular training variables, periodisation strategies, and how to adapt plans over time as clients progress. By the end of this unit, you will be able to build programmes for a wide variety of client goals, from weight management to athletic performance.
Unit 4 — Delivering Personal Training Sessions
Theoretical knowledge only matters if it translates into effective coaching on the floor. This unit covers session delivery skills including cueing, demonstration, observation, and feedback techniques. You will also look at motivation, adherence, and how to build client relationships that lead to long-term results and referrals. Practical assessments in this unit ensure your skills are evaluated in real-world conditions.
Unit 5 — Business & Professional Practice
Qualifying as a personal trainer is just the beginning. This unit prepares you for the realities of working in the fitness industry — whether that is as an employed PT in a gym or as a self-employed personal trainer running your own client base. Topics include professional standards, insurance requirements, client record keeping, pricing, and marketing yourself effectively in a competitive market.
