Yes, because as the size of your muscle increases, the mass of your muscle increases. And when the mass of your muscle increases, so does the weight.
maybe
Taylor Lautner had to gain 30 pounds of muscle to be in New Moon
yes, just remember that if you lose fat, but gain muscle, you can actually gain weight because muscle weighs more than fat. But people that have more muscle also have faster metabolisms, which allows you to burn off more calories, therefore decreasing the amount of fat that the body stores, allowing you to shed those unwanted pounds of fat.
No, you won't look very much different, especially if the last 4 pounds are muscle. To gain muscle, try doing strength workouts. DO NOT do cardiovascular workouts (like running) if you are trying to gain weight.
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.
Well if you lift weights you gain muscle right, well muscle has weight so if you gain a pound of muscle your not getting heavier your just building muscle. Bodybuilders on average weigh 200 to 280 pounds but they don't carry that extra weight in fat but they carry it in muscle. But since fat burns 60 calories a day muscle burns close to 110 calories a day so ultimately that muscle will burn all that fat you want to burn.But if you weigh 500 pounds your not extremely muscular you just fat.
2nd law of thermodynamics
Using your muscles (for example by working out) is the only way to gain muscle mass.
What you can do is eat lots of fatty food like, nuts and yougurt. These things are healthy and they help put on the pounds. You can also start working out to gain some muscle.
It's impossible to gain muscle from fat. You get muscle from heavy exercises and protein :>
If you want pounds fast, drink muscle milk and don't work out. It's got like 1,000 calories every cup.
Impossible for permanent growth, it is however possible to gain 20 to 30 pounds of muscle in a month. However if you ate a lot of high calorie dense foods and water you could probably gain 3-5 pounds of fat in a day, although I recommend it.
