Peer support has a significant impact on exercise adherence by fostering motivation, accountability, and enjoyment in physical activity. Having workout partners or participating in group classes can create a sense of community, making exercise more enjoyable and less isolating. This social engagement encourages individuals to remain committed to their fitness routines and can lead to improved performance outcomes. Additionally, shared experiences and encouragement from peers can enhance self-efficacy, reinforcing positive behaviors that promote long-term adherence to exercise.
