I am trying to exercise in ways that might improve the shape of my butt. I do not know if I am making much progress. At the gym, I can and do squat with the barbell and no additional weights. I also do weighted bridges and what I think are called hip thrusts. I do the bridges and hip thrusts with about 50 pounds extra weight in the hips. Here are some photos taken today. Perhaps I will find some from a previous month.
In the very first of these photos, if we measure using the lower part of the butt, then my waist to hips is at 79%. If we use the top of the hips, then we are at 88%.
