Step-by-step guide to Becoming a Fitness Instructor

How Much Can a Fitness Instructor Earn?

According to data collected by Glassdoor, fitness instructors can earn anywhere between €12 – 20 an hour. For employed fitness instructors, Indeed lists the average salary as €28,616.

Factors like location, experience, and number of hours worked also influence earnings. For example, fitness instructors in Dublin usually earn more than those working in rural areas.

Naturally, experience and advanced qualifications give you access to higher paying jobs and progression opportunities.

For freelance these qualifications give you access to a wider client pool, allow you to offer additional services, and charge more by marketing yourself as a specialist.

How Much Does it Cost to Become a Fitness Instructor?

A Level 3 Fitness Instructor Course can cost anywhere between €500 to over €1000, depending on the training provider. The exact cost for you to become a gym instructor depends on who your training provider is and factors such as:

  • Your Study Method – Online courses are typically cheaper than in-person or fast-track options

  • Payment Method – Some providers offer a discount if you pay the course fees in full

  • Interest Rates – If paying in instalments, keep costs down by looking for 0% interest plans

  • Hidden Fees – Cheap courses aren’t always the bargain you think, many have hidden fees for things like resits and certificates
  • Marketing – Cost does not always equal quality, some providers set higher prices to make you think that their courses are the best

Career Opportunities for a Fitness Instructor

Now you know what it takes to become a qualified gym instructor, it’s time to discuss your career options!

As an employed instructor, you can work either part or full time at a gym or fitness centre. This is a great starting point for new instructors, offering professional growth and a steady income.

When you’ve gained further experience and clients, you could choose to go freelance. Freelancers earn a fixed salary while working across multiple venues on shorter schedules. You’ll mainly teach classes when required, without additional responsibilities.

Many use employed or freelance roles as steps toward self-employment. Going solo lets you run your own classes or move your services online, allowing you to expand what you offer. You can even take your services abroad or open your own gym!
