Thank you for noticing.
Biceps are a small muscle you don't need much.
2 x 15 alt dumbbell curls 20lbs
3 x 8 alt dumbbell curls 40lbs
3 x 6 hammer curls (65lbs) I usually do some banging and swinging to get them up, then i squeeze my bicep with the weight right at the top of my chest. then release
3 x 8 concentration curls 30-35lbs
Edit: This is what works for me, I hate preacher curls, i also despise using a barbell. I always hit forearms right after with light weight and high reps.
