Exercise
Planned, structured physical activity that improves cardiovascular fitness, strength, flexibility, mood, and long-term health outcomes.
On the exam, exercise items usually arrive as teaching questions (“which statement indicates correct understanding?”) or screening questions about who needs HCP clearance first. The tell is a number: beyond the weekly aerobic target, answers often hinge on muscle-strengthening of all major muscle groups on 2 or more days per week and, for adults 65+, balance training to prevent falls. Expect the target heart rate stem — moderate effort is roughly 50–70% of (220 minus age), vigorous 70–85% — and remember the talk test: at moderate intensity you can talk but not sing. That gauges intensity, not readiness; readiness is the HCP clearance question.
Watch the related-term boundaries. Exercise is one lifestyle behavior, but item-writers crown smoking cessation the single highest-impact change, so don’t pick exercise as “most effective” overall. For obesity, exercise alone rarely produces meaningful weight loss without caloric/dietary change — the trap answer credits activity for pounds it can’t deliver. And wellness is the broad, multidimensional process; exercise is one concrete action within it, not a synonym.
