If you picture someone training their arms and chest, it's easy to picture an intense gym workout with heavy weights. Fortunately, that's not always the case—you can develop upper-body strength with just a few moves and a set of dumbbells.
If you don't already have a pair at home, we'd recommend investing in a set of adjustable dumbbells. That way, you can increase the weight as you get stronger without having to buy an entirely new set of weights.
