The natural exercise body clock
The body's biological clock -known as the circadian cycle- has a decisive role in the body's reaction to exercise. Knowing at what time of day the body is best prepared to carry out a certain physical activity, we can ensure that we make the most of our efforts.
Below is a list of the best types of exercise to carry out at different times of day. Although this is important information, we should bear in mind that everyone has their own circadian cycle (or biological oscillation of 24 hours), which can vary from the norm.

Morning hours: Body on the go
Blood flows with greater strength and there is a high hormonal activity. It is the ideal time to boost blood flow through exercise and take advantage off the high hormonal levels; activities such as running, swimming or cycling are ideal ways to achieve this. Also, at these times, the body temperature is at its highest performance levels and can be best harnessed via coordination activities, such as step sessions, aerobics or dancing.

Midday: Time to recuperate
The body is first hungry and then tired. The guilty parties are the increase in the stomach's acid levels and the decrease in the blood-sugar levels. The body wants to eat and rest, in that order. Instead of exercising, it is best to have a balanced meal and then a short siesta, (a half hour is sufficient to recuperate). After eating is also not a good time to exercise, as the body uses up most of its energy digesting.

Afternoon: Stretching, resistance and strength
In early afternoon, the body is still recuperating from its rest. It is best not to push it with over-strenuous activities, which is why stretching exercises are ideal. The reason? The muscles are especially soft and elastic, which reduces the risk of injury when tensing them. Any of the so-called soft gymnastics (yoga, Pilate method, Global Active stretching) will be welcome.
As the hours pass, the metabolism will stabilise and the body respiration will increase along with its ability to absorb oxygen. In short, the batteries are recharged. You now have enough energy for resistance sports - such as running, swimming, horse riding or skating - or strength-based sports, such as tennis or volleyball.

Blood flow is particularly active at this time; exercise that work the stomach, legs or buttocks are especially effective at this time.

As the afternoon reaches its end, reaction times improve. This is the reason why this is the ideal time to take part in a team sport. How about a game of football or a session of squash?� Take advantage of your body's physical disposition.

End of the day: Relaxation
Do not prolong exercise beyond nine in the evening. From this moment on your body is begging for a little rest. It will welcome a sauna session or a relaxing aromatic bath. It is also the perfect preparation for the hours of sleep that will help you exercise better the following day.
