This video helped me see what I was doing wrong with squats.

I did 45, and had to stop because my breathing went to hell, by virtue of the movements themselves. But in that time I felt more in my quads and latissimus dorsi than anywhere else. I'm almost certain that I'm doing it totally correctly. I just expected to feel more in the glutes.

I will work up to more. I'm going to attempt to do more every day, and still do my usual workout three times a week, for now.
