Most specifically, glute bridges work the gluteus maximus. The hip extension aspect of this exercise involves the hamstrings, and the core aspect targets the transversus abdominis. When you do this exercise with a resistance band above your knees, the gluteus medius portion of the glutes works extra hard.

You might think that glute bridges only work your butt muscles. But the exercise engages many muscle groups. This includes lower back and core muscles, hamstrings, and hip adductors (inner thigh muscles). Strengthening these muscles — plus the glutes — is critical for mobility, good posture, and injury prevention.
