You might think you need an extended gym session with loads of machines and weights to strengthen your upper body. Fortunately, that's not the case, as this four-move workout builds arm, shoulder, chest and back muscle with just a set of dumbbells.
Dumbbells are a flexible option for at-home training, especially if you opt for a set of the best adjustable dumbbells. These combine several weights in one, saving you space and allowing you to gradually increase the load as you get stronger.
