Dumbbells are a great option for strength-training anywhere—in a gym, at home, outside—because they're compact and easy to use. The key to strengthening your muscles is to keep them challenged by changing up your workout—and your exercise equipment.
When performed properly and regularly, an upper body workout can help build the lean, strong limbs that not only help you achieve the look you want, but improve your range of motion—an essential part of your ability to do everyday tasks with ease.
You have your upper body strength training routine so down pat that the weights know you’re coming over to them next even before you put your resistance band down. Kudos on your dedication to this important aspect of fitness!
