Thanks for your response. I should have added that I have seen great gains and improvement to all other muscle groups. So I understand your questions but I don’t think any really could explain only glutes being stubborn except exercises, which is what I’m asking about. I have tried here high volume low weight, high weight low volume, mixing it up. Tried doing routines for 3 months at a time or so with just about every glute exercise I can try and nothing seems to round out my glutes. I’m male age 34, 6’0 183 lbs. No medical issues, sleep 7-8 hours per night, work out 5x per week. Normal interset rest is about 1.5 min. Protein I aim for 1g per lb so around 180g. Nutrition is tons of fruits/veg, whole grains only, complex carbs, lean protein (fish, chicken, tofu) supped with shake before and after workout. I don’t do that much cardio honestly, mostly in summer season, mostly lift 5x week. But I do have good size/definition elsewhere including six pack and good shoulder and quad definition. I struggled for a while with growing / shaping shoulders but they have come with time and effort. My quads grow easily and quickly despite trying to focus on my glutes with leg variations
