For beginners who have just started fitness, there is no change in a month! After a period of training, the adaptability of the nervous system will be promoted, and the number, speed and fluency of muscle fibers will be strengthened, that is, the number of muscle fibers that can be used at the same time will increase, and the strength will naturally be displayed more smoothly. The effect of this neural adaptation is very fast, basically in 4~8 weeks.
Factors affecting muscle gain: first, your genetic structure and endocrine level. We all know that everyone's sports performance is different. Some people are born with quick reaction, long-distance running and fast metabolism. Some people are naturally athletic, some people are naturally thin, and some people are naturally fat.
It is not easy for a fitness veteran to achieve sustained muscle growth. Muscle experts, to achieve a breakthrough in muscle dimension, the bottleneck is very big. For example, a person who usually scores 60 points can improve to 90 points, which has a lot of room for improvement. People with 95 points want to improve to 98 points, and the score is not big, but they need to make greater efforts than others.
If you want to make your muscles bigger by exercising 1-2 times a week, I'm sorry to tell you that it's impossible. Only by maintaining the frequency of exercise 4-5 times a week can we ensure muscle growth. There is nothing once and for all in this world, and so is fitness. You need to constantly stimulate your muscle growth. It is suggested that each exercise time should be controlled at 40-50 minutes and aerobic exercise should be controlled at 20-40 minutes.
