'Active' describes taking part, moving, or making things happen through your own effort. 'Passive' means accepting what happens without acting, staying still or letting others take the lead. An active person exercises and initiates; a passive one waits and receives. The pair are direct opposites in both physical and figurative senses.

Regular physical activity strengthens the heart, muscles, and bones, helps manage weight, and lowers the risk of many chronic illnesses. It also boosts mood, energy, and sleep by releasing beneficial brain chemicals. Staying active doesn't require intense training — regular walking, cycling, or everyday movement all count and add up.

In the sense of physical movement, the main opposites are 'inactive', 'sedentary', and 'idle', describing little or no exercise. In behaviour, 'passive' is the key antonym, meaning unresponsive or not taking initiative. 'Lazy' and 'sluggish' are informal opposites that add a sense of reluctance to move.
