The forty-five degree leg press can be found in most gyms, offering the athlete the ability to exercise their quadriceps, hamstrings and glutes. Because the back is fully supported during the leg press, the exercise is an excellent choice for those who cannot perform the barbell squat due to spinal or upper body injuries and conditions.
The way the athlete places their feet on the platform will dedicate, to a degree, the amount of emphasis which will be placed on the quadriceps, or the hamstring and glutes. Placing the feet lower down on the platform with a normal width stance will target the quadriceps to a high degree, as greater forces are applied to the extension of the knee. On the other hand, a higher and wider stance will place greater forces on the muscles responsible for the extension of the hip, namely the glutes and hamstrings.
