If you’re like most women, you’re curious about whether doing the same routine as the men in your CrossFit class will give you the same results. On average, baseline muscle mass in men is 36% greater than in women. In terms of muscle distribution, women tend to have less upper body muscle mass compared to men.
Men have a slight genetic advantage over women because of their higher baseline muscle mass, particularly in the upper body. However, that doesn’t mean that women will gain less muscle mass than men, despite lifting the same amount of weights.
When men and women exercise for the same amount of time, they can accomplish the same amount of gains in muscle mass. While the increase in size was similar between men and women in the study, the relative strength of women actually increased more than men because they were starting with a smaller overall body size.
In addition, it’s worth noting that muscle mass gain may be more affected by individual variations in terms of sensitivity of resistance training responses rather than gender differences.
What This Means For Women:
It’s possible to gain as much muscle mass as men, but it may take more work on your end because of your slightly lower baseline muscle mass. However, if you’re worried about getting too big, it’s also unlikely to happen due to differences in testosterone (we’ll cover that later,) and how you train.
The first step toward achieving enough amount of muscle mass is to do a body composition analysis to determine how much you have. Click here to read more about the various types of BIA devices that analyse body composition.
