One question that haunts gym users is \u201cwhat is the ideal time for aerobic training?\u201d. Cardio for Increased Endurance If the goal is to increase cardiopulmonary capacity and endurance, aerobic training should be done before any other, in this way, we would have all our energy reserves available to maximize this training to the maximum. The training should be of moderate to high intensity, and the time can vary from 20 to 40 minutes depending on the physical condition of each one. Cardio for Increased Strength and Muscle Mass If the goal of the training is to increase strength or muscle mass, we must first perform the strength training, by optimizing the energy reserves to ensure a better performance in muscle contractions.\u00a0After the end of this training, you can start practicing aerobic activities.\u00a0Thus, we will use the rest of the carbohydrate reserves and the fat reserves as the main fuel for this stage.\u00a0The ideal is to perform at low intensity, an average of 20 minutes. Cardio for Weight Loss If the goal is to lose weight (decrease the percentage of fat), the practice of weight training should be prioritized before aerobic training.\u00a0This is because, when we start training with weights, we consume carbohydrate reserves, then fats act as the main source of energy during aerobic activity.\u00a0If after the end of training we do not ingest calories, we will consume more fat in this recovery period to resynthesize the sources of muscle energy spent in the activity. The ideal, in this case, is 20 to 30 minutes of low and medium intensity aerobic activities, which can be interval training or even low intensity for a longer time, everything will depend on the athlete's physical condition. In short, the human body is a machine in constant discovery.\u00a0It does not have right and wrong, but what is ideal for your organism. Personal Trainers\u00a0recommends that you review your situation and your specific goals with a\u00a0qualified professional\u00a0to remove the most out of your\u00a0specific training.
