I typically only isolate my #Biceps and #Triceps as primary muscles about 1x/week (otherwise secondary muscles on my upper body days). But when I do my #ArmWorkout I like to have at least one exercise where both arms are being used together (#BarbellBicepCurls previously posted), and another where each arm does the exercise individually. That's what we have here with these 4 sets of 8-10 reps of #AlternatingBicepCurls. You could always alter these a little bit by keeping your hands neutral, or facing each other, and turning these into #HammerCurls (which I love as well).
