Bodybuilding depends not only on the chest circumference, but also on whether the whole body muscle ratio is coordinated and whether the outline lines are full and clear. But there are also basic size standards, namely: the ratio of chest to waist is three to two; Neck circumference, upper arm circumference and lower leg circumference are basically equal. According to your height, if your waist circumference is 22 inches, then your bust should reach 33 inches (1 10 cm) to meet the bodybuilding standard. This is difficult (don't ignore the exercise of latissimus dorsi, because latissimus dorsi accounts for a large part of the chest circumference). I hope you don't get discouraged after reading it!
