The optimum time of day to work out for increased performance can vary based on individual preferences, but generally, afternoon and evening workouts tend to yield better performance levels. Studies suggest that core body temperature and hormone levels are typically higher later in the day, resulting in improved muscle function and strength. This time frame may also correlate with enhanced endurance and cardiovascular capabilities. However, personal schedules and energy levels play crucial roles in determining the best workout time. Listening to one's body and finding a time that promotes consistent engagement is key.
