The gluteal group of muscles consists of 3 muscles: Gluteus Maximus, Gluteus Medius and Gluteus Minimus. Gluteus is Greek for rump. Maximus is the largest of the muscles and Minimus the smallest. The role of the Gluteus maximus is different from the medius and minimus muscles because of their attachment points.
Many lower-body exercises engage the gluteal muscles as stabilizers, and the leg press is no exception. The gluteals are the main muscle group in the buttocks, and the leg press fully engages them during the lift phase and the control phase.
