This is a super-setting arms workout, which finishes with some necessary isometric and stretch work. A great choice if you need a quick upper-body strengthening workout that gives you a little medicine at the end. A few different sizes of dumbbells, a pull-up bar, and a bench or something similar will be needed here. If you don't have access to a pull-up bar, go for a handstand alternative.
We love these adjustable dumbbells from Rep Fitness. They take up very little space and are also very durable compared to other adjustable dumbbells on the market.
