If you want to improve the shape of your hips and thighs -- and who doesn't -- then perform leg press exercises. The lying and seated leg presses are very similar in movement, but when you are seated, you work your butt and hamstrings, or rear thigh muscles, whereas the lying leg press works your quadriceps, or front thigh muscles.

In conclusion, the seated leg press and lying leg press are two effective exercises that target the muscles of the lower body. While the seated leg press offers a limited range of motion and places more emphasis on the quadriceps, the lying leg press allows for a greater range of motion and engages the hamstrings and glutes to a higher extent.
