Social pressure, fear of failure, health shocks, and new year's resolutions can initially motivate people to exercise. However, enjoying small successes through achievable goals is the most effective long-term motivator. Setting and accomplishing incremental goals fuels further motivation in a self-sustaining cycle, making 10 minutes a day for a year more impactful than 2 hours a day for just a week. Harnessing this motivation wave allows people to sustain exercise habits over time.
