The body's circadian rhythm affects exercise performance by influencing energy levels and physical readiness throughout the day. Various physiological processes, such as hormone release and body temperature, fluctuate in line with circadian patterns, impacting peak performance times. Typically, individuals might experience higher energy and strength in the afternoon or early evening compared to morning workouts. Aligning training sessions with this natural rhythm can optimize performance, as athletes are likely to feel more alert and responsive at their body’s peak times.
