Supercharge your upper-body strength programs using this three-move dumbbell workout. It's designed to torch your arms, shoulders and core and won't involve spending an hour in the gym. Efficient (tick) and effective (tick).
I recommend a set of the best adjustable dumbbells to tackle this because you might want to adjust the weight depending on the exercise. That's optional, though — you can just use a medium-heavy set of weights.
