Lunges work the hamstring muscles when you step forward and backward. When stepping forward, the front hip and knee flex as your weight is transferred onto that leg. The hamstrings work to resist the downward pull of gravity, known as an eccentric contraction. They also help stabilize the knee.
This exercise can be utilized to work out your hips, butt and several other muscles. All three of the hip, or gluteal muscles, are worked out during lunges. The gluteus maximus is the primary muscle worked and is used extensively to extend the hips. You can target this muscle more intensely during the exercise by using very large steps.
