What are effective exercises for developing bicep muscles?

To help with appearance, don't forget your tricep, a strong and well developed tricep will help push the bicep to the upper area of the arm for the classic bicep look most people are aiming for.

Ok, try this out. (doing biceps 2x a week) 1 week do 3x8 standing db curls. Week 2, do 3x12 bi curls. Week 3 do 3x12 bi curls. And week 4, one day do 3x3, and one day do 3x5. Cycle this, meaning once youve finished the process start from the beginning again. This'll give you 3 weeks of mass reps, and 1 week of strength reps. Try and keep each 2 days apart, for example once on Mon, and once on Thurs.
