Help me gain my 3kg!!

Rakan2, help me plz..
i need the 3kg to achieve my ideal weight! hehehe.
seriously!
i've been trying for the past 3 months
but there's been no change or what so ever in my weight.
even after raya pon tak put on weight. haihh...

however..
- i need a healthy way of putting on weight.
no binging on unhealthy stuff ya!
- i want the 3kg to be evenly distributed!
takmoh filled in the tummy or thigh or cheek.
i wouldnt mind if it goes to the bum tho. hohoho
- i dont want anything like weight gain or pill product.
- i know work-up in the gym might help.
tp takde masa lah! n plus tak mampu nak pay for the membership fee.
hehehe...

so cemane ye??? =))
