Girls, are you afraid to pump up the big muscles!?
Normal testosterone levels in males – 200-1200 ng/DL (nanograms per ten liters), and for women the norm is 15-70 ng/DL. As you can see, the level of testosterone in males significantly higher than females. Even the most low testosterone levels in men (200нг/DL) is more than twice the highest testosterone levels in women (70 ng/DL).
If we take the average testosterone level in men and women, men 700 and women and 42.5. Thus, on average, the level of testosterone men have 16.47 times higher than women!
It is obvious that women have this hormonal support (testosterone) to gain muscle mass like men. Therefore, the fear to pump up too big muscles and look like Arnold Schwarzenegger in a skirt unnecessarily. You're probably thinking: "I have seen very muscular women body builders, which by their figure more like men". The reason they look is that they is likely to make the injection of exogenous testosterone or other anabolic steroids.
When women use exogenous testosterone/steroids they may have excess hair on the face and chest, increased muscle mass, the pattern of distribution of body fat varies from male to female, the voice becomes lower, but also may be other side effects.
The point is that if you do not use exogenous testosterone or other anabolic steroids you will not get big muscles, exercising with weights. This does not mean that you will not be able to increase your muscle mass, it will increase, but you won't look like a man, and will acquire a trim figure and great physical shape.
Should nutrition for women differ from power for men? Actually, no. Men and women have similar metabolism, except that women burn more fat relative to carbs. This is perhaps one of the reasons that women are good low-carb diet.
Should differ only the total number of calories consumed. Women need fewer calories because they have less muscle mass and more fat (relative to total body weight) than men. The amount of proteins, carbohydrates and fats depends on the total number of calories consumed.
