For your goal, to build muscle, your weights should be roughly 80% of the 1RM you have. For example, if your 1RM was a 40kg weight, when training you should be using roughly 80% of your 1RM so you would need a 32kg weight. Once you have the right weight, start with 3 sets. 2 sets of 8 reps and 1 set of 6 reps.

For building muscle size dumbells would be better because you can increase the weight you are using. The general rule for bulking up and building muscle is to lift heavier weights and do less reps. The best thing to do is to work out your 1RM ( 1 rep max ) To work this out, with an instructors help, you do one rep with the heaviest weight you can lift safely (which is why it is important to do this with a qualified gym instructor)

U can increase weight on barbell too,When it comes to bicep the rule is not just to lift heavy, Bicep is a very particular muscle,you need to do exercises that hit it directly and when going heavy with biceps you often miss the target because the weight is too heavy your fore arm and back begins to step in and when u go lighter or not two light with average amount of reps you get to target the bicept better..and yes this advise was given to me by a gym instructor and alot of background researc

The most common misundstanding about bicep is that u must go heavy. no you need to go within your control.Your muscle will be gettin the fatigue it needs to grow eventhough its light because lots of times when u go heavy your fore arms and back are doing everything.and the bicep just does little or nothing
