Lets talk about really weak peoples, i have met many weak and lean people saying that they eat very much and do nothing all day just are taking rest but are not gaining muscles, i want to make clear one thing if you want to gain muscles you have to eat well as well as work out well.If you will eat well and are not taking exercise or working out, all the food and calories that you have taken goes to waste without having any effect on your body.

So take good calories then work out at gym you will definitely gain muscles. Best food which is cheap and easily available for body building is white part of egg without yolk, the white part contains maximum and pure fats, take about 3-4 eggs without yolk only yellow part then work out at gym.

To gain size of muscles perform sets with heavy weights and take rest 2-3 days of week, meaning perform exercise 4-5 days in week and then take rest you will surely gain muscles.

People who are fat and already overweighted should perform as many sets of light weights as they can and try to go gym twice a day and 7 days a week, if you will stay on your schedule you will gain cuts and smart body in about 2 months

Hope you like information.

Take care
