Passive income: NO

It is unlikely that personal training can become a source of passive income for most people. Personal training typically requires active involvement, such as conducting sessions and providing personalized guidance. While some trainers may create passive income streams through online courses, apps, or subscription-based content, these often require significant upfront work and ongoing updates. Most trainers do not reach this level of passive income, as it usually involves branching into related areas like digital products or content creation. Passive income in personal training is generally achievable for a few outliers who successfully leverage their brand and expertise into scalable products.
