I don't get exercise someone plesae help?

how come people say you need to excercise to get skinny, and they also say excercise if you want to get chubby, ( like if you are too skinny)i don't get it.. someone help.

Any sort of moderate cardio exercise (swimming, walking, running) burns calories (energy) so therefore you lose weight. The more carbohydrate you consume, the harder it is to burn off all the calories. That is why some people go on "low-carb" diets, in an attempt to beat the bulge.
You need to eat healthily, and exercise at the same time. If you burn off more calories than you're taking in, then you'll lose weight. If you consume more than you're burning off, you'll gain weight. If you eat healthily, and exercise well at the same time, you'll maintain your current weight - being healthy and happy. Unfortunately some people are naturally slim or naturally big build - there's not much you can do if you're in this situation. I hope this answered your question =] xx.
