The myth of women getting “big”
This comes from the fitness magazines at stores that show grotesque women flexing their brains out. it’s interesting that on the flip side a lot of guys want to look like the guys in those magazines and will try so hard to get HUGE! like them… but do any of them actually end up looking like the big bodybuilder dude.… NO! That’s because building large amounts of muscle mass takes a lot of focus on that particular goal to do so and usually that still won’t lead to being huuuugggeee. Here are a couple other contributing factors.
The facts:
1. The truth is that building large amounts of muscle mass for any gender is actually pretty hard to do and you would usually have to focus your training and nutrition to achieve large gains in muscle mass.
2. Genetics: Genetics play a huge role in how much muscle mass one can gain. Guys typically develop muscle easier than women, although there are a select few women that can gain larger amounts of muscle due to their individual genetic make-up.
3. Women have much lower testosterone levels then men. Typically around 10–20 times less. Testosterone is known to increase protein synthesis and muscle size, so it would seem that women would have a much tougher time getting huge muscles than 
guys even if they are doing the exact same training. Guess what, the women in the “flex” magazines are on steroids which help to increase their testosterone levels.
4. How can women gain strength and not be bulky? Most of the time, women beginners wills tart gaining strength at a similar rate to male beginners. This is mostly due to different neurological factors. The neural system is typically less developed in females and strength gains will typically be a result of an increase in the efficiency of the neural system rather than an increase in muscle mass. For the guys, they will probably see more of an increase in muscle mass.
5. Nutrition: Nutrition plays a huge factor in the development of muscle mass. If you want to increase your muscle mass after the beginning phases of training you will also need to focus your nutrition to achieve that goal. To make things simpler: you would have to eat more food. So if you don’t want to gain muscle mass then eat a proper diet that will keep you at a bodyweight that you are comfortable with. It is nearly impossible to gain weight/bulk if you aren’t eating an excess amount of calories that your body doesn’t need.
