Which type of motivation tends to support long-term adherence to exercise?

• A. Intrinsic motivation
• B. Amotivation
• C. Introjected motivation
• D. Extrinsic motivation

Answer: (A)

Intrinsic motivation drives long-term adherence because people participate in exercise for its own sake—the activity is enjoyable, interesting, or personally rewarding. When the behavior is self-determined and comes from within, it becomes a habit that people want to continue even when external rewards or pressures are removed. This internal pull helps sustain consistent effort, progression, and integration of exercise into daily life.

In contrast, motivation based on external rewards or pressures tends to be less durable. External rewards (appearance goals, praise, or financial incentives) can wane, and people may stop exercising when those rewards disappear. Internal pressures (such as guilt or obligation) can be motivating in the short term but often fade and may lead to burnout. A lack of motivation, or amotivation, means there’s no drive to act at all, which also undermines long-term adherence.
