There are lots of posts out there in the interwebz about people having problems with squat. Everyone of all shapes and sizes has some sort of problem, especially at first, but even further along. You just have to work on correcting it.
Recently someone posted a video of a competition between 4 lifters doing squat, as many as possible in a certain amount of time. The powerlifter was really tall and gangly. The bodybuilder was tall and build well. The weightlifter was short, thin and perfectly proportioned. The strongman was short and overweight. The tall and gangly powerlifter won the contest. His size was not a handicap at all.
Female, 5'3", 49, Starting weight: 163lbs. Current weight: 135 (more or less).
I can squat 180lbs, press 72.5lbs and deadlift 185lbs
