It depends on your purspose and what you are free to do. When I joined the Army I started hetting more than regular exercise and eating three high calorie square meals a day. In four months I gained almost twenty five pounds of muscle. This was without weight traing, just calisthenics and running. I imagine if you started to have bigger more nutritious meals and alternate lifting weights and running you could buff up quite a bit. It all depends on if you want be a body builder or just buff.
You really don't need to worry about it. Gaining muscle is not that easy, especially when you have 5% the testosterone of men. Additionally, there is no such thing as toning muscle vs. adding bulk. You either add muscle or you don't - if you want more definition then reduce your body fat. Women, like men, should be strength training with a barbell.
Generally you will gain about 2 pounds of muscle a month when body building when you are a strict beginner and working really hard at eating proper. If you are gaining much more then that I would be concerned that it isn't all muscle gain.
you may get muscle growth any time from now until about a little before you end puberty. some effects of puberty come out really late in some people
he was really bad at it.
It really all depends you could weight 135 and be normal or weight 90 and be normal. Height makes a change in this the taller you are you might weight a little bit more. Muscle also can make you weigh more if you exersise a lot you could just be gaining muscle weight.
If you were anorexic, you probably lost a lot of muscle mass. It will take you a while to build back muscle and muscle is where you burn calories. Try building muscle mass. Eat plenty of calories and specifically 60 to 80 protein grams or more and exercise to build back muscle mass. You really need to get healthy again and you'll only do that by building muscle.
The simple thought to losing some weight "Am I burning as much or more than I eat?" Running for half an hour will burn some calories, so I am assuming that you will lose some weight. There is no set place that you lose the weight at. If most of your fat is stored at your stomach, then you will probably lose some there. From running, you will probably lose some in your legs and gain some muscle. Don't be freaked out by the thought of gaining muscle. In women, muscle makes you lean and appear to be thinner than you really are. In men, muscles make you buff. So whatever gender you are, gaining muscle is a good thing. One thing you might want to do is vary your exercise program a bit from time to time. Doing so helps to prevent overworking those select muscle groups. I would suggest mixing in some weights or other arm exercises.
Well, there is a balance between strength and muscle size. If you want to get really strong, you'll have to accept having really big muscles. But if you just want to get stronger, then the key is to exercise on a sensible level. If you keep the weights so that you can do 3 sets of 10 repetitions, or even 4 sets of 10 reps, muscle growth won't be that much.

Your best bet would be to stop working out. Keep a healthy diet and exercise regimen, but don't over do it. It doesn't take long for your body to start losing muscle mass, but as long as you eat healthy and exercise regularly, you should have no problems with gaining weight, or fat, for that matter.
