When you’re not looking to build muscle, but rather maintain what you’ve already got, it can be tricky to find the right exercises. This video breaks down four simple arm exercises for muscle maintenance that you can do at home with a set of dumbbells. It also breaks down the proper form for each exercise, so you can get the most out of your workout while staying safe. Plus, since there’s nothing quite like a workout video from the ‘80s, this video incorporates those loud patterns and vibrant colors – as well as the nostalgic synth music of the decade – to make your fitness routine that much more fun.
