Because they lack testosterone

Mostly it is because there are microscopic tears in your muscle...\nAnd as they repair, that's how you build up the muscle.

Males tend to be stronger and faster.\n\nI hate people that disagree with this statement and feel it's a put down to women.  It's not, it's genetics, it happens, why is it so hard to grasp?

why would pregnant women have it any harder than non-pregnant or men?  Other than walking up and down the steps...

Yes, it is most assuredly possible for a female to build muscle mass without turning into a body-builder. Regular, intense swimming can develop the sort of long, smooth muscles you seem to want. I recommend you contact a local gym which can offer you expert advice about the best approach. \n\nYou already have a healthy diet, now add the physical development necessary to build the muscle mass and you'll be dyno-mite!  :D

Simply put, female athletes would not be able to compete with bigger, stronger males. Not to discredit the athletic ability of women. The sexes are built differently and men are favored in the athletic arenas requiring speed, power, and strength (though not necessarily in all sports- ultramarathons).

You can't gain muscle.... you have a certain amount of muscle and you are not going to get anymore. But you can tone and/or add bulk.  Nutrition and exercise both play an important role.   One without the other will not give you what your body needs.  You need balance.

bcos u guys may be strong from the outside but are weak from the inside ie strong physically but weak mentally. we women may be weak physically but mentally we are very strong. we can take much more pain and suffering and we can undertand better due to that. u need someone to be beside u not only when ur happy but even in pain. thats y a women is so important cos they fulfill every need and want of a man

Defintion comes more from diet. Drink a lot more water, and cut down on fat. The abs tend to be one of the hardest areas to define, so be patient.\n Plus, girls, you don't generally have the genetics to get "bodybuilder" anything, so there's no need to worry about that.

Because they are less heavily built.  On average men are taller, burlier, more muscular and hav thicker bones.  Women do not need huge manly feet as they are smaller and thus do not need to balance as much weight.

women usually don't produce enough testosterone to build big muscles, but having a layer of fat on top of the muscle will make your arms look big rather than toned.  Work on lowering your body fat percentage by doing cardio for 30 minutes five days a week.  Make sure to use your arms, don't hold safety bars on machines.  After a month of this, add toning to your routine; use light (5-10 lb) dumbells and do 3-5 sets of 12-15 reps of curls and lifts.

easier as long as you realize that your weight will vary (due to water and muscle mass) and not get discouraged.  remember as you gain muscle mass, muscle is heavier then fat.

Most women cannot bulk up, no matter how heavy of a weight they use.  If you gain muscle size easily, stick to the light weights with higher reps.  If you don't gain muscle size very easily, go ahead an mix it up.  Use heavy weights some days with low reps and light weights with high reps other days.

I'm not a woman, but I wanted to put my two cents in.\n\nActually, according to researchers, pound for pound, woman are stronger than men.\n\nAlso according to researchers, because woman have had more of a "back seat" role for many, many years and because of the way that boys and girls are raised differently, researchers believe that if boys and girls were raised the same, that the female would be the better athlete.\n\nWhat can you do about this?  I'm not sure if anything will work, but try to "restructure" your mind with the knowledge that, pound for pound you can do better than a man.\n\nI know this is vague, but its all I've got.\n\nGood luck to you.  Keep on fighting, hang in there and you may surprise yourself.\n\nBe well.
