I’ve been working them out for about 2.5 years now. But I’ve expanded and changed my leg routine over that time.

For the first 1.5 years, I simply did squats and lunges. Those two exercises alone were tough enough to destroy my entire glutes for a few days.
Squats would be 5 sets, 10 reps, with increasing weight each set. Lunges were 2 sets, 10 reps each leg. I normally hold dumbbells for those.

Eventually I tried/added straight legged deadlifts, booty band exercises, barbell pelvic thrusts, Bulgarian split Squats, etc. I don’t do all those in a workout; that’d be too much. But those do provide a good variety. Hopefully this helps!
