When is the best time to exercise?

The best time to exercise can depend on individual preferences and goals, but research suggests several optimal windows:

1. Morning Workouts: Exercising in the morning is generally beneficial. It helps increase alertness and core body temperature, setting a positive tone for the day. This timing also aids cognitive function for at least two hours post-workout, making it ideal before engaging in mental tasks 1 2.

2. Post-Waking and Mid-Morning: The best times suggested are either immediately after waking or within three hours of waking. These times align with natural physiological changes like rising body temperature and cortisol levels 2.

3. Late Afternoon for Performance: Some studies indicate that strength and performance might peak in the late afternoon (around 11 hours after waking) when body temperature is highest 3. However, this varies by individual.

4. Regularity is Key: Ultimately, consistency in exercise is more important than the exact timing. Regular activity, whether in the morning or afternoon, yields health benefits 3 4.

5. Cortisol and Sleep Considerations: Exercising too late in the day may disrupt sleep due to increased cortisol levels. Therefore, earlier workouts tend to promote better sleep hygiene 5.

In summary, while morning workouts may offer cognitive advantages and better alignment with circadian rhythms, the most important factor is finding a time that fits your lifestyle and allows for consistent exercise.
