What factor can substantially contribute to participants’ enjoyment of aquatic fitness classes?

Social interaction and communication play a vital role in enhancing participants' enjoyment of aquatic fitness classes. When individuals engage with others, it fosters a sense of community and belonging, making the experience more enjoyable and motivating. The enjoyment often stems from the camaraderie and support that comes from sharing a common goal—improving fitness levels together.

In a group setting, participants can encourage one another, share experiences, and create friendships, which makes the classes feel more like a social event rather than just a workout. This interaction can also enhance accountability, as participants may feel more committed to attend classes when they know others are depending on their presence.

Other options, such as the availability of equipment or strict routines, may contribute to the structure of the class but do not inherently enhance enjoyment to the same degree as social interaction. For example, while having equipment can assist in providing a variety of exercises, it doesn't necessarily engage participants on a personal level. Similarly, strict routines with no variability could lead to boredom and might decrease enjoyment due to lack of engagement or creativity in the workout.
