Assess the ability to apply the FITT principle by designing a 4-week progressive exercise plan for a Grade 6–8 student that targets cardiovascular endurance and muscular strength. The plan should specify Frequency, Intensity, Time, and Type for each week, include age-appropriate sample activities, warm-up/cool-down, safety/modification notes, measurable short-term goals, and a simple method to track progress and justify how the progression supports expected outcomes.
