Which of the following is a common barrier to maintaining a fitness routine?

Lack of motivation and time is indeed a common barrier to maintaining a fitness routine. Many individuals struggle to find the motivation needed to stick with an exercise program, especially when faced with the demands of daily life. Time constraints can exacerbate this issue, as busy schedules often leave little room for physical activity. When people do not feel motivated or lack time to commit, they may abandon their fitness plans altogether, making it difficult to establish and maintain a consistent routine.

In contrast, access to facilities and equipment is less of a barrier for those who are determined to maintain fitness; many people exercise effectively with minimal resources or adapt their routines to fit available options. Having a supportive community typically serves as an enhancer of motivation and accountability rather than a barrier. It's also important to note that being physically fit doesn't impede one’s ability to maintain a routine; rather, it can enhance the enjoyment and outcomes of the fitness activities.
