actually keta, its more than just that for sum ppl.
look dude if u wanan build muscle, do a routine that uses your whole body, if you're a beginner, try training 3 times a week (mon, wed and fri, or tue, thur and sat) training your whole body (ie: Chest, Back, Legs, Shoulders, etc) using your weight set and body weight execises. Have u considered joining a gym too? This may help as if you dont feel you have enough equipment than this could be a better alternative than raking up the money to buy lots of weights and gym equipemnt. Although you could check out rebel sport, they have good 50Kg weight sets for pretty cheap. I need more at the moment, i quickly out lifted my 50Kg set lol.
Also in conjuntion with this, make sure you eat well, get enough protein for muscle repair, carbs for energy, and try to keep fat from healthy sources (minimal saturated, but get plenty from good sources such as unroasted nuts, fish, etc). Eat ever 2-3 hours and have 6 meals instead of 3. You sound as if you have a fast metabolism so you probably wont have trouble with gaining body fat, as you sound really slim anyway. Make sure you eat clean foods too, no fried or junk foods or foods high in processed and refined sugars.
Rest is also paramount in building muscle so aim to get around 8 hours or more a night.
Hope this helps you out bro.
Also remember to be consistant and keep pushing on and tryin your best bro! Good luck.
