Times are a bit different now that we’ve made it through 2020. In 2019, you’d be laughed out of the boss’s office in most cases if you told him you’d be working from home. It was all you could do to beg for that extra 30 minutes so you could head to the gym for a quick workout.

Even though many are now heading back into the office, a hybrid lifestyle is about to become the norm. Combine all that extra time with your love of staying fit, and you’ve got an excellent foundation for a side hustle.

Side hustles are exploding as the office work schedule is imploding, and now is the time to start generating another source of income doing something you already love to do.

5 Fit Side Hustles Anyone Can Do

There’s a saying that goes something like, “If you do what you love, then you’ll never work a day in your life.” 

This used to be applied to a career search but doing something in health or fitness that didn’t involve perfect grades and expensive school was extremely difficult.

Now, though, there are several options for you to pick from while still grinding away at your day job (and capitalizing on that hybrid office schedule).

Personal trainer

Becoming a personal trainer is relatively simple, which is why it’s one of the first side hustles that fitness-minded entrepreneurs turn to. There are a few downsides to this choice, the first of which is that you need to be the right sort of person and go after the right sort of client. High energy coaches with a knack for motivating people do well as personal trainers. You’ll also find that most workout facilities will require you to get a certification of some kind before they’ll let you take on clients. The last consideration is that you may depend on an hourly rate.

That’s where there’s good news. The hourly rate for a personal trainer could be up to $75 once you’ve got a reputation. Even on the low end at $23 per hour, you can still make a decent side income.

Social Media Fitness Mentor

These are all over social media, and some are better than others. It can take the most time and effort, but it can also be the most rewarding if you approach it the right way. While some social media accounts are primarily about advertising and collecting money from posts, many people are offering fitness programming and using social media to advertise their products. Fitness Programming is where you create fitness workout plans for clients, sometimes even diet plans, and guide them through the process to see success.

Eventually, many offer their own fitness products to help clients, such as supplements, fitness gear, and other merchandise. This side hustle is truly a hustle, but it doesn’t necessarily require a certification and it’s one where you could see the most success especially online. One strategy is to start a blog, write about your own experiences from using various supplements (such as protein powder, creatine, pre workouts etc.), listing the pros and cons; then recommending your own line or a favourite brand (where you can earn a commission from promoting it).

Group fitness instructor

From yoga studios to CrossFit boxes, instructing in group fitness classes has become the ideal side gig for several reasons. While you’ll still be required to obtain a certification before getting the job, the group fitness industry is expanding quickly, offering several niche options for those not interested in throwing barbells around.

If you already go to such a facility and you love it there, it can’t hurt to ask the owner what their requirements are and whether they’d have a spot for you. If you take enough classes on a regular basis, some facilities have been known to not only pay you for classes but also give you free membership! If your membership costs $150-200 per month, that’s already a bonus just for starting!


This one might be the most technical and highest stress, but it can be the most rewarding for the right person. There are usually plenty of opportunities to referee or umpire in your local community. Obviously, you’ll have to go through a relatively rigorous course to get certified. Once you do, you’ll be able to jump into games and start gaining experience.

While referee pay is relatively low, for those who love the games it can be an extremely rewarding experience. Sometimes a side gig is about extra income, but other times it can just be about enjoying life a bit more. Being a referee is also a great gig for weekends if your job isn’t too keen on letting you do other things on your home days.


You might be asking what this is doing on the list. If you’ve ever hired movers, you know there is some heavy lifting involved, and it could take hours in a day or even spread to several days. After a moving gig, you’re guaranteed to be exhausted like you’ve just run a marathon.

The money isn’t that great, but some of the gig-type sites such as Bellhops allow movees to tip their movers. The sky is technically the limit, but this one is mostly about getting a good workout in.


Your parents might have told you to pick a degree that would land you a well-paying job with benefits rather than pursue your love of coaching, refereeing, or going for World’s Strongest Man. With the gig economy expanding every day and work schedules loosening to allow the time to build them, side hustles are almost a no-brainer. There are several options specifically for the fitness-minded, and they can result in not only a stream of income but a more fulfilled life.
