Social support plays a critical role in fitness adherence by providing motivation, accountability, and encouragement. When individuals engage in physical activities with friends, family, or community groups, they are more likely to stick to their fitness plans due to shared experiences. This collective involvement helps in overcoming obstacles and fosters a sense of belonging. Additionally, having emotional support can reduce feelings of isolation and enhance mental well-being. Studies suggest that individuals with strong social ties are more motivated to pursue their health goals, making social support a key factor in long-term fitness success.
