Exercising in the morning often feels more challenging due to the body's natural circadian rhythm, which influences hormones and core body temperature. Most people experience their peak physical performance, including strength and endurance, during the late afternoon and early evening, typically between 4 pm and 7 pm. Factors contributing to reduced morning performance include lower core body temperature, higher insulin levels affecting blood sugar, and less efficient nervous system signalling to muscles. An individual's sleep chronotype, such as being a 'night owl', can significantly impact their ability to perform well during morning workouts. While the body can adapt to morning exercise over several weeks, the overall benefits for general fitness and health remain consistent regardless of the time of day.
