Course Overview

If you’re looking for a career as a Personal Trainer, or to validate your experience, then the fitness industry’s most respected Diploma – The Level 3 Diploma In Fitness Instructing & Personal Training is for you. Upon successful completion of the course you will be authorised to work in the health & fitness industry as a Personal Trainer or set up your own business.

This Diploma consists of two primary qualifications including the Active IQ level 2 Certificate in Fitness Instructing & Active IQ Level 3 Certificate in Personal Training.  Our Personal Trainer course has been developed over the 20 years we have been in business, aligned with the standards of the current fitness industry. We train you for a sustainable career as a Personal Trainer, not just a fitness qualification.

Why train with The Fitness Circle?

We impart experience and actionable knowledge. It is a fact the health and fitness industry is booming in response to the general decline in the health of the population. On the upside, there is an immense opportunity and increased demand for fitness professionals. Training with us gives you a strong foundation and competitive edge for a job in the fitness industry.

Frequently Asked Questions

Why take the Diploma in Personal Fitness Instructing?

Our fully online Diploma in Personal Fitness Instructing gives you an in-depth course that takes you from beginner to expert. Combining the Level 2 and Level 3 courses ensures a complete knowledge of fitness and nutrition principles. 

The diploma is a pathway to a long-term career in the fitness industry, enabling you to save money by combining both courses. 

Is your Diploma in Personal Fitness Instructing a recognised qualification?

Yes, it is. Our courses are accredited by the CIMSPA (Chartered Institute for the Management of Sport and Physical Activity). Upon completion, you’ll gain an industry-recognised qualification demonstrating your professional knowledge. 

Employers hold CIMSPA-certified PTs in high regard, and many of our students work in the UK’s most reputable gyms and fitness centres. 

What is a Level 3 PT in the UK?

A Level 3 personal trainer is a highly qualified professional who can work in a variety of settings. Level 2 gym instructors are entry-level employees, but personal trainers might work one-on-one with clients, or in a large fitness centre, helping people reach their goals. 

Many PTs choose self-employment, which allows for more flexibility, while others might work with specific demographics. Having a Level 3 qualification opens many doors for a profitable career. 

How much can I earn as a personal trainer?

It depends on where you work and whether you’re an employee or self-employed. Figures from Indeed place the average salary at £30,452 – but self-employed trainers can earn £60,000 a year or more. 

How long is the Personal Fitness Instructing Diploma?

Our diploma combines two courses into one convenient learning experience. Most people complete the course over a year, but it depends on whether you’re studying full-time or fitting the course around work and other commitments. 

Do I need qualifications to be an online personal trainer?

Although online training seems easier than coaching people physically, it requires more knowledge. Many trainers begin their careers in gyms and health centres and become self-employed when they have experience. 

You will need a qualification to train people online, as you’re still responsible for their exercise plan and diet. Qualifications are essential unless you’re working in an unofficial capacity with family and friends. 

What if I need support with my course?

We have a team of dedicated tutors ready to offer support and advice throughout your course. The materials are designed to provide a complete learning experience, with case studies, practical training videos and ongoing support. 

If you have any questions, reach out to your tutor, and they’ll get back to you.
