Level 2 vs Level 3 Personal Training Courses: What’s the Difference?

Over 22,000 new fitness professionals qualified in the UK last year—and most started with a Level 2 or Level 3 course.

So, what’s the difference between the two? And which one gets you closer to your dream career?

Whether you’re aiming to break into the gym floor or build your own PT empire, this guide will break down everything you need to know about Level 2 Gym Instructor vs Level 3 Personal Training qualifications—so you can choose the best path for your goals.

A summary of key differences between Level 2 and Level 3 personal training courses:

1. The Level 2 Gym Instructor course is for people who want to specialise in instructing gym-based exercise and helping clients develop healthier fitness behaviours. The entry-level course will teach you foundational, practical skills that you can apply to a gym setting and is ideal for beginners.

2. The Level 3 Personal Trainer diploma is an advanced fitness training course that will help you develop vital skills to support clients with fitness, health and nutrition. The qualification also covers business acumen and teaches you how to provide professional personal training services.

3. While the Level 3 PT diploma is ideal for progressing through different personal trainer levels into management or starting your own business, the Level 2 Gym Instructor course is perfect for beginners.

Our Level 2 Gym Instructor certification is a gateway into the fitness industry. If you’re new to health and fitness altogether, investing in this course is a great way to understand foundational principles and find entry-level jobs.

The Level 3 Personal Trainer Diploma

If you want to take your career to new levels, such as supporting clients one-on-one in a gym or fitness centre, becoming a qualified personal trainer is a great decision. This level 3 course gives you advanced knowledge of fitness principles and prepares you to work with clients of all experience levels.

Upon completion of the Level 2 Personal Trainer qualification, you can:

• Create personalised training programmes for clients of all abilities

• Support clients by offering nutrition advice

• Conduct personal training sessions

• Open your own personal training business

Our prices start at £750, and students can gain their personal training qualification in their own time. The course also offers flexible payment options.

Is it best to begin with the Level 2 or Level 3 qualification?

The certification you choose will depend on multiple factors, including your experience levels and career goals. While some people are happy to focus on entry-level roles, others want to develop professional careers and open their own businesses.

While the Level 2 Gym Instructor course is ideal for beginners, investing in a Level 3 qualification gives you more opportunities for the future. However, you’ll need a foundational qualification before applying for the personal trainer diploma.

If you want to combine courses, our Online Personal Trainer Course combines both the Level 2 Gym Instructor and Level 3 Personal Trainer certifications.

Which career paths does each course offer?

While both courses offer unique benefits, the one you choose should reflect your career goals. Let’s take a look at how each course will impact your employment options.

The Level 2 Gym Instructor Course

When you gain a Level 2 Gym Instructor qualification, you can enjoy a diverse career with plenty of opportunities to help clients develop their fitness. Gym instructing involves teaching people how to use equipment, assisting personal trainers, and supervising classes.

With our Level 2 Group Training certificate, you can also specialise as a group instructor. The course lets you conduct group training sessions, which enhances your employment options and ensures you can take on more responsibility in a gym setting.

The Level 3 Personal Training Diploma

When you have a personal training qualification, you can work in a range of environments, including gyms, health centres, and boot camps, and open your own business. Many trainers begin by working with clients from all backgrounds, but there’s the opportunity to specialise.

For example, some PTs work with athletes, helping them prepare for major events, while others might support bodybuilders with conditioning.

You can also advance into management roles while taking a Level 4 Personal Trainer diploma, which is ideal if you want to become self-employed.

Earning potential

Many fitness professionals choose their careers because they’re genuinely passionate about health and want to help their clients succeed. However, knowing how much you can earn is a significant part of choosing your qualifications.

It’s important to remember that your earning potential will increase as you gain experience, but the average salaries are as follows:

Gym instructor salary

Newly qualified gym instructors earn around £17,000 a year, while experienced instructors earn up to £27,000 yearly.

Personal trainer salary

Personal trainers have an average salary of £30,000 a year, but newly qualified trainers might earn less. With experience, you could earn over £40,000; the potential is practically unlimited if you start your own business.

Which personal training qualification should you choose?

With so many personal trainer courses to choose between, knowing where to start can be a challenge. However, once you understand what you’d like to achieve with your career, choosing a course that suits your needs is easier.

• The Level 2 Course: This course is best for people who are new to the fitness industry and have little experience. It teaches foundational principles that will prepare you for entry-level roles in gyms and other fitness settings.

• The Level 3 Course: If you want to build a career as a successful fitness professional, the Level 3 PT diploma prepares you to work with clients on a one-to-one basis. Once you gain experience, you can explore other personal training levels and enter management roles.

Combining the two courses into one affordable diploma can save time and money if you want the best of both worlds.
