Everyone responds differently to training different body parts and you have to experiment over time what works best for you.I would suggest the following for biceps:
Standing barbell curls 4 x 10
Alternate dumbell curls 4 x 10
Barbell preacher curls 4 x 10
**work biceps with either back or on a day with triceps**
I like doing a same-muscle superset:
1-A)Close-Grip Supinated Chins 2-3x4-6 reps/30 sec rest
1-B)Incline Dumbell Curls or Zottman Curls 2-3x8-10/3 min rest
Athletes program is much like mine and it's worked for me, except I do incline dumbell curls instead of regular db curls to hit bi's in the stretch position, and only do 3 sets of each exercise.
