Make money online: NO

Starting a gym as a side hustle can be possible remotely if you focus on online personal training or creating digital fitness programs. However, if you plan on opening a physical gym location, it will require in-person presence. Online reviews suggest that remote fitness coaching can be successful if you have a strong online presence and market your services effectively. The success of this side hustle may depend on your location, access to clients worldwide, time zones for virtual coaching sessions, and availability of necessary equipment. Red flags to consider include the need for marketing expertise and competition in the online fitness industry.
