The Science-Backed Truth"},"content":{"rendered":"

When you walk into any gym, chances are you will find that a common trend is men having their way in the weight room while women are doing cardio machines and light dumbbells.<\/span> When questioned as to why, most women refer to the same thing: they are afraid of becoming fat.<\/span><\/p>\n

This myth has ensured that too many women are never allowed to enjoy the amazing fruits of <\/span>strength training<\/a><\/strong>.<\/span> Enough of the fable of fitness, and let us get down to real science.<\/span><\/p>\n

The Myth of the Bulky: Its Origin<\/b><\/h2>\n

The bulking fear is based on a fundamental misconception of the mechanism of <\/span>muscle growth<\/a><\/strong> and decades of marketing in the fitness industry, which educated women that they should remain toned using light weights and high reps.<\/span><\/p>\n

The photos of female bodybuilders, although spectacular, confirmed the notion that, when one lifts heavy, he or she is bound to get enormous muscles.<\/span> However, here is something most human beings fail to understand: such bodies take years of rigorous exercising, special dieting and in many cases, the use of performance-enhancing drugs.<\/span><\/p>\n

The female who averagely works out in the gym in weightlifting will not wake up in the morning as a bodybuilder and the jogger will not wake up as an Olympic runner.<\/span><\/p>\n

\"Muscle\"<\/p>\n

The Biology: Why Women Are Not That Easy to Bulk Up<\/b><\/h2>\n

Testosterone Matters<\/b><\/h3>\n

Testosterone<\/a><\/strong> is the main active ingredient for muscle development.<\/span> It is a natural process for women to produce 15-20 times less testosterone than men.<\/span> It is a hormonal disparity that implies that women find it much more difficult to gain large quantities of muscle mass even when they are willing to do so.<\/span><\/p>\n

Women would gain muscle when they strength train, but at a very slow pace compared to men.<\/span> A woman who is serious about training may put on 5-10 pounds in the first year of training and a man may put on 15-25 pounds under the same conditions.<\/span><\/p>\n

Muscle Size vs. Muscle Definition<\/b><\/h3>\n

What women consider as being bulky is either muscle definition due to body fat loss, or swelling of the muscles (so-called pump) right after exercising.<\/span><\/p>\n

When you begin to exercise with the weights, you will find that your muscles are more noticeable.<\/span> This is not due to the fact that you have developed huge quantities of muscle overnight.<\/span> It is because you are losing body fat, clarifying previously existing muscle, or the fluid retention is temporary in the muscles.<\/span><\/p>\n

The Math Doesn’t Add Up<\/b><\/h3>\n

To build a lot of muscle, you have to have a caloric surplus, i.e., you must consume more calories than you are burning.<\/span> The majority of women who are afraid of adding on excess weight are in caloric deficit or maintaining their diets, attempting to lose weight or remain lean.<\/span><\/p>\n

It is impossible to accidentally gain large muscles as you eat in a deficit.<\/span> Physiologically, it cannot be.<\/span> In order to build new muscle tissue, your body requires additional energy and nutrients.<\/span><\/p>\n

\"Muscle\"<\/p>\n

What Actually Happens <\/b>When Women Lift Heavy<\/b><\/a>?<\/b><\/h2>\n

You Get Stronger, Not Bigger<\/b><\/h3>\n

During the initial few months of training, the majority of the strength gains are a result of neuromuscular adaptations, your nervous system learning to recruit muscle fibers more efficiently, and not developing new muscle.<\/span><\/p>\n

You will be pushing a bigger weight, and be stronger, but you may not even see any difference in measurements.<\/span> When questioned by many women, it is shocking to learn that they can increase their squat strength without their thighs growing larger; they actually grow smaller as they become fat-free.<\/span><\/p>\n

Your body constitution becomes better<\/b><\/h3>\n

Muscle is denser than fat. <\/span>The space occupied by a pound of muscle is less than that of a pound of fat.<\/span> Once you start to build muscle and lose fat at the same time (so-called body recomposition), you tend to become smaller and more defined, not bigger.<\/span><\/p>\n

A large number of women who thought that they would reveal themselves as bulky note that they have actually dropped down a size or two in their clothes after regular weight training, although their weight remains the same or increased on the scale.<\/span><\/p>\n

Your Metabolism Increases<\/b><\/h3>\n

The muscle tissue is metabolic in nature and this implies that it utilizes calories even when resting.<\/span> Muscle helps to build a higher resting <\/span>metabolism <\/a><\/strong>rate and thus it becomes easier to keep good weight over a long period.<\/span><\/p>\n

The Real Benefits Women Miss Out On<\/b>\u00a0<\/span><\/h2>\n
