What is the best time of day to exercise?

The best time to exercise is whenever you can do it consistently, as adherence matters more than timing. That said, research suggests some advantages to different times. Morning exercise tends to boost metabolism, improve mood throughout the day, and is easier to stick to since fewer conflicts arise. Afternoon and early evening workouts often align with peak body temperature and muscle function, which can improve strength and performance. If you're training for athletic performance, late afternoon around 4-6 PM may offer a slight edge. If you struggle with motivation or a busy schedule, morning is often the most practical choice. Ultimately, the best time is the time you'll actually show up and do it regularly.
