Ready to make money from your love of fitness?

1. Online Personal Training

Since Covid, online personal training has seen a sharp rise.

People are seeing the benefits of working out with a virtual personal trainer, when they couldn’t get to the gym.

If you’ve worked as a personal trainer before, or have a niche fitness credential, you could train clients via a training app.

Training ideas to make money could be postpartum fitness, muscle building for 40-year-old guys or Pilates for example.

Set your services up on a fit app such as:


2. Group Fitness Instructor

Do you go to fitness classes yourself? If yes, being a group fitness instructor is an ideal fitness side hustle for you.

Fitness instructors earn £20 – £50 an hour in England, depending on what the class is and which city you’re in.

Reach out to your local gym and ask what the process is to become an instructor. There may be a short course you can take, to get the right qualifications.

One great thing about teaching fitness classes is the flexible schedule. Once you’re qualified, pick classes and times that work for you.


3. Dog Walking

Dog walking is a top fitness side hustle where you can set your own hours and rates.

There are many dog walking apps such as RoverWag Walking and Barkly Pets that pay people to walk precious pooches.

Once you become active on these platforms, you’ll get to know people and their dogs, which may score you regular work.

Many dog walkers charge up to £50 per walk, so you can see how lucrative this side hustle can be!


4. Freelance Fitness Writer

Do you have a way with words and love all things fitness?

If you have experience in the health and fitness space, you could earn side hustle cash writing for fitness blogs and local health brands.

Every business needs content written to promote its products. And, specialised writers get paid even more.

If you know about running, Pilates, muscle building, nutrition or anything else health-related, you can earn decent money writing niche content.

Search ‘’fitness writers’’ in the job section of remote job sites.

Or set up on large freelance marketplaces such as Upwork or Guru as a specialised health and fitness writer.

More freelance writing content you may like:


5. Personal Meal Prepper

Do you love cooking healthy and know your good carbs from your bad carbs?

Have you lost weight on a certain diet? If healthy meal prepping is your thing, you could earn money by helping others with their diet.

People have busy lives and need guidance to eat healthily. You could set yourself up as a personal meal prepper and write specific meal plans for their goals.

And don’t worry, you won’t have to cook. Just order the meals via meal prep companies such as Muscle Meals 2 Go or Meal Pro.


6. Health and Fitness Blogging

Thousands of people type into Google ‘’how to get fit’’, ‘’beginner workout’’ and ‘’fitness plans’’ daily.

If you know how to get fit and have the results to show, a health and fitness blog is a way to share your knowledge and make money.

Choose a catchy name for your blog, buy your domain hosting and launch your blog on WordPress for a few dollars a month.

If you want to try fitness writing for free to begin with, start on Medium which connects you with millions of monthly readers.


7. YouTube Fitness Channel

In case you’ve been living under a rock for a while, YouTube is massive and video content is growing in popularity every year.

Many YouTubers make millions each year from their channels through adverts, brand sponsorships, promoting affiliate products and selling their own products.

Fitness is big on YouTube and it grew during lockdown when boredom set in and people went to the platform to find free workout videos.

For inspiration, go and look at some of the top fitness YouTube channels:


8. Organise a Walking Group

Are you a hiker or runner? If yes, there’s an opportunity here to turn this love into a lucrative fitness side hustle.

You can start for free and charge those who want to join you a small fee.

People will pay for a guide who knows the best trails, runs or even a bit about local history. Taking a group out helps others get fit and you can make some cash.

Advertise on your Instagram or Facebook accounts. And post flyers about your neighbourhood to drum up interest.


9. Sell Print on Demand Fitness Apparel

Do you have a cool fitness brand idea? Or maybe a few funny fitness slogans in mind?

Unique fitness wear is big business, so why not start your own print-on-demand (POD) business online?

All you need to do is create the designs which you can do for free on Canva.

Next, upload your designs to platforms such as:

When someone makes an order, your design will be printed onto a product and delivered.

The company takes care of delivery and customer service so you can relax and enjoy earning passive income.


10. Influencer for Active Wear

Do you have a large following on Instagram, Twitter, Tik Tok or Facebook?

Brands will pay you to advertise their apparel. As your followers grow, you may get approached by brands to do paid promotions.

Fitness influencers are in demand. You could possibly earn hundreds, to thousands just for one shoutout post.

The top influencers earn tens of thousands per post! For example, Kayla Itsines who is a hugely successful Instagram fitness influencer and has 12.5 million followers, reportedly demands $59,304 per post!!

Check out some of these influencer platforms to get started:


11. Sell Fitness Online Courses

Many fitness trainers and coaches create and sell training programs to a target audience on e-learning platforms.

This can become a lucrative fitness side hustle and involves designing specific workout routines such as:

  • Weight loss for Moms
  • Strength training for guys
  • How to lose belly fat
  • How to tone up arms

These courses are often bought by those who may have little time and prefer to workout at home, so the course would need to cater to this.

Other information that would help in your course would be giving nutritional advice, tips on how to track progress and you could even offer added coaching calls for an extra fee.

To succeed with this personal trainer side hustle, you’ll need great communication skills, an approachable and positive manner and a great image on social media platforms that help people trust you.

12. Sell Fitness Products in an Online Store

Another great side hustle for sports enthusiasts and fitness gurus is to start an online store selling fitness apparel or supplements.

Start by doing a little market research and see what products are popular in Shopify stores and on other online marketplaces such as Etsy and Amazon.

If you have a great following on social media who buy your fitness programs and watch your fitness videos, it’s likely they trust you and will buy physical products from you.

You can have supplements made by a third-party manufacturer and sold through your own label.

Or, you can create a fitness brand selling t-shirts and hoodies and these can be printed and delivered for you by a print-on-demand company.

13. Fitness Podcast

start a podcast

Another side gig idea is to share your fitness knowledge with a wider audience via a podcast.

This will involve you recording audio shows and discussing health and fitness-related subjects, such as:

  • Nutrition
  • Healthy lifestyle
  • Mental health
  • Niche workout plans
  • Fitness goals and how to conquer them
  • Personal experiences
  • Interview fitness experts

To make this a success, you will need the ability to engage an audience, communicate well and write interesting podcast episodes that people want to listen to.

But, once you get a listener base, you can monetize your podcast episodes with sponsorships, adverts and patron donations.

14. One-On-One Training Sessions

​If you’re a certified personal trainer you can provide one-on-one personal training sessions to people in your local area.

This will include:

  • Assessing a client’s needs
  • Understanding their goals
  • Working with them to provide a custom training program that gets results

If you’re starting out, this can be done in your free time as a side gig, until you build up enough clients to go full-time.

And, training sessions can be done anywhere that suits, including in the park, in the gym or in a client’s home.

The average pay for PT is around $20 – $100 an hour, depending on your experience.

15. Publish a Fitness Newsletter


Another one of the best fitness side hustles is to start a health and wellness newsletter.

The work will include you capturing people’s email addresses which can be done through your blog (if you have one) or by promoting it on social media.

Next, you need to zero in on a niche topic that you’ll write about in your newsletter that aligns with your passion and knowledge.

A few ideas include motivational content, nutrition tips or workout routine ideas.

Once you have your newsletter running, you can start to monetize with:

  • Affiliate marketing
  • Paid subscriptions
  • Selling your own products or courses
  • Advertising for fitness brands

Just be sure to keep providing value to your subscribers and only promote stuff you know will help them.
