Marketing influences fitness behavior by shaping perceptions of health trends, products, and services. Effective campaigns can motivate individuals to engage in physical activity by highlighting benefits and creating aspirational images of fitness. However, misleading information may promote unrealistic body standards and unsustainable practices. Social media also plays a pivotal role in spreading fitness trends, impacting how people perceive exercise and nutrition. Awareness of marketing tactics is vital to make informed decisions regarding fitness and health-related choices.
