Social support enhances adherence to a fitness program by creating a network of motivation and accountability. Friends, family, and workout groups provide encouragement, which can lead to increased consistency in exercise routines. Social interactions also foster a sense of belonging and camaraderie, making workouts more enjoyable. Participating in group activities can reduce feelings of isolation and boost morale, especially during challenges. Having a support system encourages goal setting and shared achievements, ultimately leading to better long-term engagement with fitness programs.
