The American College of Sports Medicine (ACSM) identifies five components of fitness: cardiorespiratory endurance, muscular strength, muscular endurance, flexibility, and body composition.
If Ivan is focusing on these specific components, he does not need to include skill-related components of fitness such as agility, balance, coordination, power, and reaction time in his baseline measurements. These skill-related components are important for athletic performance but are not part of the ACSM's five health-related components of fitness.
