Progress in the first weeks

I noticed some changes after workout 3 in the first week, and there was a slight but further increase in size on workout 5 (even before the workout). I'm using progressive overload every 4 workouts for squats, and the remaining exercises advance every 2 weeks. So progressive overload is every 1-2 weeks and it's per exercise more than per workout.

There was an additional challenge in understanding the exercise order, which is explained by the Stronglifts site as 5 sets per exercise, for a total of 15-20 minutes per exercise, making the workout 45-60 minutes. At this time I kind of disagree with that and am doing the workout in the order of 1 set per 3 exercises, and the workout is 20 minutes. That seems to make more sense, but correct me if I'm wrong. I've just never seen a workout where you do 1 exercise for 15 minutes, then a second and a third for the same duration. If that's the way to do it in the end, I'll have to make the change, but I remember last time I followed the progressive overload advice of adding weight every workout, and it lead to overtraining.

I am making slow progress with my way of doing it so far. I'll post an update if there are any changes.
