Cardio - Training:
Before programming your training, it is essential to take account of your age, particularly for people of more than 35 years of age, as well as your physical condition. If you have a sedentary lifestyle without regular physical activity, it is vital that you consult your doctor to determine the level of intensity of your training. Once determined, do not attempt to achieve your maximum during the first training sessions. Be patient; your performance will quickly improve.
This enables you to develop your cardiovascular system (fitness of the heart / blood vessels). During Cardio-Training, the muscles need a supply of oxygen and nutritive substances. They also need to limit waste. Our heart increases its rhythm and sends a larger amount of oxygen to the body by means of the cardiovascular system.
The more often you exercise regularly and repetitively, the more your heart will develop, just like any other muscle. In daily life, this translates into the ability to bear greater physical effort and improve your intellectual faculties.
Definition of your work Zone:
The Maximum Heart Rate (MHR) = 220 - age (180 - age for sedentary people).
The Warming Up Zone and Cooling Down Zone are equal to 55% of your MHR.
The Fat Loss Zone is between 55 / 65% of your MHR.
The Aerobic Zone is between 65 / 85% of your MHR.
The Anaerobic Zone is between 85% of your MHR and your MHR.

The progressive training stages:
1) A warming up phase:
Start each training session by warming up progressively (10-20 min, more if you are over 50) which will put your muscles on standby and gently increase your heart rate. Gently increase your pulse to 55% of your MHR (Maximum Heart Rate).
Keep your Heart Rate at this level for the duration of the warming up time. If you begin your training too quickly, you are in danger of increasing the risk of tendon or muscle injury.
2) A work phase:
This is the main part of the training session. Depending on your specific goals and your initial physical condition, weight loss, improvement of cardiovascular resistance (aerobic work), development of stamina (anaerobic work), it is possible to choose the appropriate target zone.
The Fat Loss Zone, 55 - 65%
The heart rate must be low and the duration of the exercise quite long. This zone is advised for people resuming physical activity after a long period of idleness, who
are trying to eliminate excess weight or are susceptible to cardiac problems. Do not forget that for this type of training the duration of the exercise must be at least 30 minutes and the Heart Rate (HR) between 55 and 65% of the MHR. - Gradually increase from 30 to 60 minutes per session.
Exercise 3 or 4 times a week.
The Aerobic Zone, 65-85%
This zone is recommended for those who are in good physical condition who train regularly. By training in this zone, you will improve your physical condition but avoid overworking.
Duration: 20 to 30 minutes per session.
- Frequency: At least 3 or 4 times a week.
The Anaerobic Zone, 85% - MHR
This zone is exclusively for experienced athletes and is never recommended without medical approval and supervision. This zone is designed only for very fit people. It is used for interval training (or for short sprints) to help you to improve or measure your level of stamina. The time spent in this zone must be brief to avoid the risk of accident.
3) A cooling down phase:
This entails a reduction of exertion (10 to 20 min). It enables you to return your cardiovascular system to normal (55% of your MHR) and prevent or reduce muscular pain such as cramp and stiffness. You must follow the training with a session of stretching exercises while your joints
are still warm. This relaxes the muscles and helps to prevent stiffness. Stretch slowly and gently. You must never stretch until you reach the pain threshold. Hold each stretch for 30 to 60 seconds while breathing out.
Check your progress
As it improves, your cardiovascular system will have an HR which will be lower when at rest. You will take longer to reach your target zone and it will be easier for you to maintain it. Sessions will seem easier and easier and you will have more stamina in your daily life.
If, on the other hand, your HR is higher than usual when at rest, you will have to rest or reduce the intensity of your training.
Do not be discouraged by the initial sessions. Motivate yourself by scheduling specific training times. Work hard!
