You don't need to spend hours in the gym lifting heavy weights to build muscular arms. You can achieve good upper body strength at home with just a set of dumbbells. 

Personal trainer Ally Aslaksen recently shared a low-impact workout that strengthens your arms and works your core in roughly 20 minutes. The moves are all done on the floor with a set of light weights, so it’s a good option if you don’t fancy a long, arduous session in the gym. You can watch the full workout here.
