looking to add some size to my bi's. I hear so many different opinions so i want to see what some of you guys think. I usually start out with 4 sets staright bar (reps 12-10-8-6), then I do alternating dumbell curls or hammer curls (10-10-8-8), then i do a preacher machine that has three different weight racks for concentration on each part of the Bicep (10-10-10), then a cable exercise usually (12-10-10-8).....what do you guys think, should I change the order or reps? I am thinking of doing less reps higher weight same work out....
