What action does an aerobics instructor likely take to encourage higher knee lifts?

Modeling the behavior is an effective strategy for encouraging higher knee lifts during aerobics because it allows participants to see the exact action being performed. When the instructor demonstrates the movement, it provides a clear example for participants to follow, which can enhance their understanding of the correct form and technique. This method is especially impactful in a dynamic exercise setting, where visual learning can be more effective than verbal cues alone.

Yelling instructions might create a more chaotic environment and does not provide a visual reference for participants to emulate. Increasing the music volume could energize the class but does not directly address the physical technique required for higher knee lifts. Using visual aids can support learning but may not provide the immediate physical example that modeling does, making it less effective in this particular situation.
