Assess the ability to design a 30-minute aerobic workout for a middle school (grades 6–8) student using age-based target heart rate zones and perceived exertion to set intensity and rest intervals. Require a brief warm-up and cool-down, calculation or description of target BPM ranges (with formula), work/rest interval structure (durations and RPE/HR targets), activity examples, monitoring/safety adaptations, and a short rationale linking chosen zones, RPE levels, and progression strategy.
