when to workout

The optimal time to work out can vary based on individual schedules, body temperature rhythms, and specific goals. According to Andrew Huberman, there are a few key considerations:

1. Morning Workouts:

   • Exercising early in the day can shift cortisol spikes, promoting wakefulness and better sleep at night 1.
   • Early morning exercise, within an hour of waking and no later than three hours after waking, sets a neurochemical context for heightened arousal and mental acuity throughout the day, often resulting in more energy and less lethargy 2.

2. Body Temperature Rhythms:

   • Peaks in body temperature can also guide optimal workout times. Huberman mentions that exercising about 30 minutes after waking, three hours after waking, or eleven hours after waking aligns with natural body temperature rises, leading to better performance and reduced injury risk 3 4.

3. Personal Preference and Regularity:

   • Regularity is crucial. Establishing a consistent workout schedule, even if it is late at night, can maintain the benefits of exercise. Consistency, rather than the specific time of day, can help sustain motivation and physical improvements 4 5.

In summary, while early morning workouts have numerous benefits, the best time to work out ultimately depends on individual schedules and preferences. Consistency and aligning with natural body rhythms appear to be key factors in maximizing workout benefits.
