According to the subject's question, I thought about it, because I am not particularly thin myself, but I also have some good suggestions for the landlord.
First of all, for people who are slightly thin, weight is not something to worry about, because it is definitely not high. For example, if the body mass index is below 2 1, I first suggest that the subject can gain weight moderately, such as eating more chicken breast to increase his protein content and fat intake. At the same time, use the right amount of vegetables to achieve a balanced diet.
When you exercise, you can do aerobic exercise for 20 minutes at the beginning. I suggest that the best running speed should not be too fast or too slow. The best state is to be able to breathe smoothly. It is the best aerobic exercise. After 20 minutes of aerobic exercise, you can start to join anaerobic exercise. Generally, you can choose some instruments to practice. You can ask the coaches there, and you don't have to list them one by one.
Generally speaking, a fitness time should not be too long, and it should be controlled between 1 hour and 2 hours. If the time is too short, it won't work. It won't work. If it takes a long time, it will be harmful to the body and will accelerate its own physical damage.
Aerobic exercise burns fat, while anaerobic exercise increases muscle. This combination can achieve good results, and it will certainly have an effect if it persists. Taking a hot bath after fitness is good for your health.
