Trainers love band workouts because they're really great for targeting the muscles in the butt—the gluteus maximus, gluteus medius, and gluteus minimus. Bonus: A resistance band is one of the most inexpensive, convenient pieces of workout equipment you can own. You can get a pack online for $10 or less, and they take up essentially no space—perfect for anyone's home gym. Try out this 10-move band butt workout next time leg day rolls around.
