Social media influences fitness trends by shaping public perceptions, introducing new workout styles, and creating communities around health and wellness. Platforms provide access to fitness experts, influencers, and peer support, encouraging individuals to engage in various activities. Trends often arise through viral challenges, routines, or diet regimens shared online, leading to widespread participation. However, the impact of social media can be double-edged, as it may foster unrealistic comparisons and promote unhealthy behaviors. Being mindful of content consumption is vital for maintaining a positive fitness journey.
