buy ezy bar+ 6 ft barbell bar+db 20 kg+adjustable bench.. ok already.. if wanna grow big, don't do many reps.. 3-5 per rep.. make sure bloody heavy that u r able to lift 3-5 times only.. if 20kg too light doing 5 x 5 , then do 8-10. x 3. if still too light , u need to buy more plates..

good luck..n please rest accordingly..if not enough rest no big muscle also just sore muscle.
