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

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