The leg press is an exercise you can do with a weight machine to work a variety of muscles in the lower body. Specifically, the leg press targets the quadriceps muscles in the front of the thighs, the gluteal muscles in the buttocks, the hamstring muscles in the back of the thighs, and the calves, all in an integrated fashion. Since the leg press works several muscles at once, it's an especially efficient way to strengthen your lower body.
