One common reason people give up on exercise programs is the lack of motivation. When initial enthusiasm wanes, individuals may find it difficult to stay committed, especially if they don't see quick results. Additionally, unrealistic expectations, such as rapid weight loss or significant fitness improvements, can lead to frustration and subsequent burnout. A lack of social support or accountability can also contribute, making it hard to stay engaged. Setting achievable goals, celebrating small victories, and finding an enjoyable form of exercise can help mitigate these challenges and promote long-term adherence.
