Lunges are a good exercise for strengthening, sculpting and building several muscles/muscle groups, including the quadriceps (or thighs), the gluteus maximus (or buttocks) as well as the hamstrings. A long lunge emphasizes the use of the gluteals whereas a short lunge emphasizes the quadriceps. The lunge is a basic movement that is fairly simple to do for beginner athletes.

A lunge can be performed using bodyweight alone. However, weight trainers may seek to increase the difficulty using either dumbbells or kettlebells held in each hand, or a barbell held atop the neck and shoulders. Grip strength may be an issue with the dumbbell lunge so practitioners may prefer the barbell lunge.
