I'd like to hear the group's opinion on the following idea I've been kicking around. Suppose a kept a dumbbell at my desk at all times. Let's suppose I can curl this dumbbell 10 times. If I were to regularly curl this weight or use it for tricep extensions, say at least four times a day for about 3-5 reps, would this provide enough stimulus for growth? I am suggesting this approach because I don't really enjoy doing isolation movements after all the compound lifts I do, but I still want larger arms.
