The Best Workout Splits for Women

For starters, women can't get as big as some people think. You might have seen images like this around the internet before; some people can't see them enough!
Of course, anabolic steroids change the game totally, which we don't recommend. But that is how women can get "abnormally" large.
The same can be said of men; they can train for 10-20 years but still not get significantly larger. This is because of the muscle growth "ceiling effect".
Sadly, regardless of our gender, we can't just keep growing noticeable levels of muscle mass week in and week out.
So, what are the facts around female muscle growth? Can they grow as much muscle mass as men?
You bet.
Research shows women can grow the same amount, and can actually gain more strength than men!
Research also shows when muscle mass is the same between both sexes, women actually have a higher rate of muscle protein synthesis!
Also, in a study of 813 volunteer elite athletes across 15 sporting categories, females boasted 85% as much muscle as their male counterparts.
The difference in muscle mass between the genders comes down to multiple factors, including that women need roughly 12 percent body fat to keep their hormones in check compared to men's 3 percent .
Research shows that birth control pills can decrease androgen levels, whereby growth factor levels are lost and cortisol increases.
In the study, two groups of young healthy women (18-29 years old) performed 10 weeks of whole-body resistance training. They did it for three days per week, 3 sets, with 6-10 repetitions at 75% of their one-rep max, totalling 13 exercises.
The researchers found:
"Oral contraceptive use impaired lean mass gains in young women after RET and was associated with lower DHEA, DHEAS, and IGF-1 and higher cortisol."
The researchers concluded that "the diminished lean mass gain may be related to the effect of oral contraceptives on anabolic and catabolic hormone levels ..."
And on the topic of muscle-building hormones, let's take a look at testosterone levels in women, and why they can grow muscle without it!
It's a fair question to ponder: why can men and women grow the same amount of muscle if men have more testosterone?
Well, this is because testosterone isn't the only thing that governs muscle growth, and in fact, it isn't needed for muscle growth in women.
Women can grow muscle mass utilising the power of hormones like IGF-1 and growth hormone, which more or less stand in for testosterone.
In fact, research shows that in women, IGF-1 performs a "gender-specific" influence on muscle strength. Moreover, women have just as much IGF-1 as men, but three times more growth hormone!
It seems women swap out testosterone with the other anabolic hormones and can then gain the same amount of muscle mass as men.
And contrary to popular belief, estrogen plays a key role too.
Ask anyone about estrogen, and they'll tell you it's an evil hormone for both sexes that is not conducive to muscle growth whatsoever.
But for women, this couldn't be further from the truth!
Estrogen actually helps muscle recovery, is anti-catabolic (prevents loss of gains!), and can protect tendons, bones and joints from injury.
The bottom line is that women can grow muscle at the same rate as men, may be able to gain more strength, and actually have a higher rate of muscle protein synthesis.
Women have 85% of the muscle mass as men and rely on IGF-1 and growth hormone as opposed to testosterone, to grow muscle. They also rely on estrogen: it actually helps muscle recovery, is anti-catabolic, and can protect tendons, bones and joints from injury.
Women looking to grow maximal muscle should avoid contraceptive pills, as they decrease androgen levels, growth factor levels, and boost cortisol, which translates into less muscle growth.
Like many, Dayne was once desperate to lose weight and get into shape. But everyone he asked, everything he read, lead to the same place... nowhere.
His journey started there - researching science journals and completing a Sports Nutrition Specialist qualification so he could make weight loss easier.
