Key Takeaways

  • If you want to stay in the realm of fitness, consider corporate or pop-up classes, or even content. 

  • As a lazier alternative to fitness, I recommend using Freecash to work from home. 

  • For something exciting and novel, consider freelance modelling.

Personal training, whether you do it at your local gym, or through an app, is a great profession that allows you to stay healthy while working. But if you're finding it difficult to find clients, here are some side hustle suggestions to earn extra money. 

Find locals looking for pop-up classes 

Besides gyms and fitness apps, there are also more casual clients you could be reaching locally. You could teach group sessions at your local park, which are more accessible, and should appeal to those intimidated by the gym

You get to keep 100% of the revenue teaching pop-up classes in the park, and you can schedule the sessions for exactly when you want. It might also lead to you finding more one on one clients, who use the pop-up class as a stepping stone to more intense fitness. 

The only obvious downside with running pop-up classes in the park is that you're beholden to the weather, and we don't all live in California. But at least during the summer months, this could provide a great way for you to make extra money as a personal trainer. 

To begin, I recommend creating a pamphlet (you can get professionally designed pamphlets for as little as $30 on Fiverr) and then either printing a few thousand copies to post locally, or upload it to NextDoor with a post to your neighbors.  

Start modelling 

While becoming a full-time model would require a lot more work and preparation than you want for a side-gig, you probably have the physique to at least find freelance modelling work

Many of these gigs only expect entry-level models, and to get started, all you will need are some professional photos to submit with your application (which can be as cheap as $200 if you're prepared to travel to the photographer).

You may even be able to find work from home opportunities, which, although rare, do exist on sites like Upwork. For instance, at the time of writing, there is an advert looking for female fitness models to take photos at home. This is for a gym brand who need to produce authentic-looking social media content, and they are paying a fixed $100 for only a handful of selfies wearing their equipment. 

With a strong application, modelling could allow you to make money as a personal trainer every weekend. And you would be doing something less physically intense than your day job. 

Use Freecash to earn from home  

I wanted to include just one suggestion that requires no physical activity, and which can in fact be done from bed, for those personal fitness coaches who want some downtime with their side hustle. And for that, a task a site like Freecash is perfect. 

On Freecash, you earn money from your phone or laptop by completing tasks online, from testing new games to answering surveys. And when you want to cash out, you can do so instantly via bank transfer or PayPal. 

The money varies, with average users making about $35 daily, and top earners making over $5000 a month. But if you can make it onto the leaderboard, you will also earn additional bonuses up to $500.

Of course, this is the opposite of an active side hustle, but as mentioned, it could be a good option for personal fitness coaches that want a more relaxing side gig. You can check out the Trustpilot here to see what other users have to say. 

Offer nutrition coaching

As a personal trainer, there's a very good chance you eat healthily, or at least you look like you do (if it's McDonald's three times a week, skip this suggestion). And you could apply your experience of healthy eating to a side hustle as a nutrition coach.

'Nutritionist' isn't a protected term in the US, so you could call yourself one and begin today without any formal accreditation. However, I highly recommend you do actually take an online course if you're serious about this idea, they only range from $100-$400, and it could provide a lot of valuable advice.  

Once you're accredited (or not), you can upsell this service to your fitness clients, or offer it on dedicated platforms like Kickoff

As this side hustle overlaps with your profession, it should also help you find more personal training clients. 

Produce fitness content and monetize it with affiliate marketing 

Fitness is one of the most popular content niches, from YouTube workouts to quick tips on TikTok. As a personal trainer, you're perfectly qualified to begin making this content yourself, but to help monetize it, you should also learn about affiliate marketing

Put simply, this involves promoting fitness products and providing a link to the products in your video descriptions. Whenever someone buys the product through your link, you will earn a small commission. A great form of passive income.

The most convenient retailer to start this with is Amazon, who have a strong affiliate program and millions of products to choose from. But be disciplined with yourself and only promote products that you genuinely like, it will be far more sustainable for your brand long-term.

Look for corporate wellness gigs 

Although this is still only an emerging industry, the idea of corporate wellness is on the rise, and it could provide a way for you to make money as a personal trainer on the side.

If you haven't heard of the concept, it largely involves employee group fitness sessions at the start of the day. The idea is that employers pay for their staff to be fitter, and as a result they (hopefully) see fewer people calling in sick. 

These jobs are difficult to find—your best bet is on a platform like Trainerize—but I wanted to include the suggestion because it can provide a great side hustle.

You will most likely start and finish these sessions very early in the day, they won't be strenuous (every employee needs to be able to participate), and like all things corporate, the money is great
