In our strength program, we will never use exercises that isolate 1 muscle group. For example, we will never do just arm curls, calf raisies, or wrist curls. (This is different from Activation where we may only want one muscle group working).
One exercise that we will do as an upper body push exercise is the Alternating Arm Dumbbell Curl and Press. What I like about it is that it is two exercises combined into one. We will do this exercise last on our Upper Push/Hamstring days for 3 sets of 8 reps each arm.
