Key findings
Fitness social media significantly predicted intrinsic motivation (β=0.396), intention (β=0.254), and behavior (β=0.295). Indirect effects totaled 33.55% of the total effect (motivation 18.57%, intention 10.75%, chain 4.25%).
Methodology
Ran an April 2025 online snowball survey of active social-media users (n=425), measured fitness social media use, intrinsic motivation, exercise intention, and behavior, then tested a chained mediation SEM with 5,000 bootstrap resamples.
Limitations
Cross-sectional self-report cannot prove causation; snowball sampling of regular exercisers limits generalizability to sedentary or offline populations.
