The concept of 30 minutes is not very accurate In fact, it means that you can start to consume fat after a period of exercise, so as to achieve the ideal weight loss effect. The effect of fitness is related to the intensity and frequency of exercise besides the time of exercise. Usually we do housework, take a walk and so on. Although the time is not long enough, we can also consume energy.
The following is the basis for judging whether fitness is really effective:
Muscle pain:
After a period of exercise, we will feel muscle aches.
This is because exercise produces lactic acid, which accumulates in muscles and causes muscle soreness.
We must persist at this time!
Moderately increasing the amount of exercise, promoting the decomposition of lactic acid, is helpful to relieve muscle soreness.
Physical pain:
If we feel pain in a certain part of the body during fitness, then reduce the number of exercises or the range of exercises.
This kind of pain is caused by slight damage to the tiny muscle fibers or ligaments of the body.
Proper adjustment can recover quickly, but if you continue to exercise, it will cause large muscles or the whole ligament damage.
Are you numb?
If a certain part of our body is numb during fitness, it means that this part has lost some of its sensory and motor functions.
Stop exercising immediately, and if it is serious, seek medical advice in time.
