When is the best time for strength training: morning, noon, or evening?

Every strength athlete wonders what time of day their muscles are most efficient. Researchers have provided clear answers.

The timing of strength training plays a crucial role in the body's performance. According to the health magazine Health, late afternoon and early evening are the times when the body's strength reaches its peak. 

The circadian rhythm as a cause

The body is geared towards a 24-hour clock, also known as the circadian rhythm. The circadian rhythm is responsible for regulating body temperature, blood pressure, and the sleep-wake cycle. It also significantly influences muscle strength, which is generally greater later in the day because the neuromuscular system is more alert, the body is more flexible due to the higher core temperature, and more energy is available from previously consumed calories. 

Morning workouts are not automatically worse

However, this doesn't mean you can't train in the morning. Increasing muscle strength during individual training sessions is most effective later in the day. A protein-rich diet can further support muscle growth.

Does exercising in the evening affect your sleep?

Don't worry, training in the evening doesn't automatically lead to a decline in sleep quality. However, you should make sure to train with sufficient time between your workout and bedtime, ideally in the afternoon or early evening. In this case, physical activity can even contribute to deeper sleep and improve energy levels and cognitive function. Training later in the day also reduces the risk of injury, as body temperature is highest then and muscles are therefore most flexible. 

Training at the same time every day – is that a good idea?

The body performs better over time when you train at the same time every day. Even if you exercise in the morning and make it a routine, studies show that morning strength eventually approaches evening strength. The overall increase in strength and muscle size was also similar, regardless of the time of day. This suggests that a consistent training routine is more important than the time of day alone. Therefore, it makes sense to train when it best fits into your schedule, establish this routine, and listen to your body.

Sometimes timing is still important.

Especially when training for a specific event or preparing for a performance test, training at the same time every day can give you a slight advantage in terms of neuromuscular readiness, or the way your brain and muscles work together. This allows you to act quickly and powerfully, which makes all the difference in competition!
