If you have a pull-up bar (and are already quite strong), there’s no doubt pull-ups are one of the best bodyweight exercises for strengthening your arms and shoulders. However, they’re a very difficult exercise and for most people a more accessible and effective way to train the upper body is using a set of dumbbells.
This dumbbell workout has been put together by YouTube fitness trainer Caroline Girvan and it’s one of the most popular arm workouts on the platform, with 6.8 million views to date. That speaks to its suitability for a wide range of fitness levels, and its accessibility — you just need 20 minutes and a set of dumbbells to do it. Or better yet, a set of the best adjustable dumbbells, so you can change the weight to suit different exercises as and when required.
