Some people always think that short-term exercise is bad for their health, but it is too tiring to stay healthy for a long time. For the average person, it is best to have enough exercise time for one hour. A friend asked why. In fact, the efficiency and time of fitness are not directly proportional to a certain extent. The longer you stay in the gym, the worse the fitness effect. In psychology, we focus on fitness, sports and other activities for about 40 minutes, and then as time goes by, our attention will decline. As we all know, whether innervation can lift weights, especially in strength training, the mind should pay attention to muscles and feel their contraction in order to achieve the best exercise effect.

However, if the single training time exceeds this time, the attention will drop and the nervous system will change, so the probability of exercise deformation, injury and strength decline will increase, which will directly lead to your fitness failing to achieve the expected effect. Especially for friends who have just started exercising, they often get twice the result with half the effort. In fact, if they exercise for too long, they may have some emotional disgust and fatigue.

However, we often choose the training intensity, ignoring the key details caused by the training volume as the key to improve the training effect. Training volume refers to the degree and duration of fitness exercise, and training intensity can represent load, speed, rest time and so on. Especially those friends with high fitness standards, the training time can be shortened appropriately, but the training intensity can not be less.

So how can we exercise in just 40-60 minutes and achieve the desired results? We must concentrate on improving the intensity of training. First, we should increase our training load, increase the weight or the number of groups, and then strictly control the rest time between each group. It is important to control the rest time.

Pay attention to every training now, this is the right way. The longer the training time, the easier it is to lead to overtraining, and everyone should avoid it. Only by paying attention to the process of physical changes during exercise can your exercise achieve the effect of strengthening your body.
