My one min stuff is mostly hips and ribs and head with the LOA put down first. Sometimes I have time to ground the pose and get in the shoulder positions too. I feel like you're missing the point of these warm up sketches. It's to loosen you up and get you out of the details, to get you to see the entire shape and flow of what you're drawing.
I know it seems counter intuitive but try slowing down, you're not there to make finished drawings, you are trying to learn to intuit what the basic shapes of a human are and where to put them relative to each other. If you put the 4 foundational shapes down, you should then be able to work out the rest of the body without even looking at the model.
I hope that helps x
