i've been on and off with working out for the past 5 years, but i've always had a similar problem. I have recently begun working out consistently about a month a nd a half ago. I've never seemed to be able to add size to my upper body. It seems no matter how much i bench it seems only my arms and shoulders are getting the workout. Am I not doing enough chest sets or not focusing hard enough??? All advice is welcomed. BTW i usually do 5 sets bench- 12/10/8/6/4 with increasing weights, 3 sets chest fly 12/10/8, 3 sets incline press 12/10/8 and 3 sets decline 12/10/8
