Which is a common barrier to good fitness?

A common barrier to good fitness is the fear of looking foolish, which can significantly impact an individual's willingness to engage in physical activity. This fear often stems from concerns about judgment or embarrassment in public settings, such as gyms or during group activities. When individuals worry about how they may be perceived by others, they may choose to avoid exercise altogether, hindering their fitness goals and overall health.

The other options mention positive aspects of fitness activities. Low costs and minimal equipment indicate accessibility and the potential for widespread participation, while being part of school sports suggests that fitness can also be a communal and supportive experience. These elements can actually encourage participation rather than serve as barriers. In contrast, the fear of looking foolish is an emotional barrier that can discourage even those who have access to resources or interest in being active.
