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.
The gluteal muscles are three muscles in the buttocks. This is atypical injury and it is more well-known to happen to runners and dancers. Gluteal tension can be provoked by:  1  overexerting the gluteal muscles and stressing it.   abruptly straining the gluteal muscles when unprepared or warmed-up.
