hi guys, im new to this forum and im very impressed with the knowledge you guys have of bulking up e.t.c. i also started workin out bout 1yr and half ago, i worked out for about a yr just using a chest expander, rowing machine and doin press ups, the results were suprising i widened found an increase in chest muscles (pecs) and shoulders, however my arms were not that big at this stage so i started doing some wieght training started at about 12kg and slowly increase dthis to about 20kg as my strenght increased. Now i can see my biceps have got mor toned and my bicep muscles are not round football shape but longer and thicker but i try work out once every so often, i do about 3 reps of 20,20,15 of each arm then i take soya protein shake, does anyone have any advice for me on how to improve on this, i am 16, 6 ft 2, around 170 pounds
