Crush This Arm-Strengthening Workout in Just 20 Minutes! All You Need Is a Mini Band

If you don't have access to dumbbells or barbells, you can still strengthen your upper body using just a mini resistance band and your own body weight. Le Sweat founder and certified strength and conditioning specialist Charlee Atkins shared this quick 20-minute workout that targets the biceps, triceps, shoulders, chest, and upper back. If you have a mini band lying around and aren't sure how to use it, try this low-impact workout or "mobility tune-up," as Atkins calls it.

First, Atkins walks you through a warmup, and you won't want to skip it because it involves a little yoga and it feels so good! Throughout the rest of the workout, you'll love her positive energy that will inspire you to stick with it the entire 20 minutes. There's a little Down Dog stretching at the end, but feel free to add on a few more upper-body stretches like these.
