Three glute-training principles.

1. Hip-hinge exercises over squat-dominant. Romanian deadlifts, hip thrusts, kettlebell swings train glutes more directly than squats.
2. Progressive overload. Glutes are a big muscle; they respond to heavier weight over time.
3. Full range of motion. Complete hip extension at the top of each rep.

Hip thrusts 3x8-12 twice a week + consistent progressive overload produces visible change in 8-12 weeks.
