Working out with a resistance band is an efficient way to lose inches and sculpt your body. Here's why: Resistance bands provide constant tension during the workout and target more muscles in the process. Plus, they're inexpensive and lightweight – perfect for strength-training on-the-go. Try these firming workouts on alternative days and achieve a leaner, firmer figure in just three weeks!
