The Psychology of Seasonal Motivation

September is often described as the “second January” in the fitness world, bringing a wave of renewed motivation. Behavioral scientists have identified this as the “fresh start effect”. These are moments in time that feel like natural opportunities to reset habits. Transitions such as the start of a new season, school year, or month can give people the psychological boost needed to begin or recommit to fitness routines (Dai et al., 2014).

The fall season provides a unique combination of external factors that reinforce motivation. Cooler weather makes outdoor exercise more enjoyable, structured schedules return after the summer, and the looming holiday season provides a clear target for goal setting. These contextual cues help exercisers feel like they are turning a new page, which can increase adherence.

Capitalizing on this seasonal momentum means setting realistic goals and building routines that can extend into the winter months. Fitness enthusiasts who start small, whether with consistent strength sessions, daily walks, or improved nutrition habits can carry the sense of a “fresh start” well beyond September. The psychological shift offered by the season can be as impactful as the physical training itself.
