The amazing effect of a year of fitness: thin people become muscular men. Compared with one year of fitness, six months of fitness is almost the same. No breakthrough. This is already a bottleneck period. The fitness plan is to practice five times a week and eat more! Only in this way can we have more nutrition for muscle growth! Good sleep can make muscles grow and recover! In fact, the theory of muscle growth is very simple: it is to exercise muscles (thoroughly exercise muscles)+supplement nutrition (raw materials for muscle growth)+rest (time for muscle repair) = muscle growth and fitness is not easy, healthy and cherished! Fitness people are iron all day, where can they get muscles without calluses? These are all evidence of muscle growth!
