I disagree with that part in PP. Many women do just fine on a single set of five on the deads for a good long while. Some need more than that, but I don't recommend doing three sets of five for deads off the bat unless there is a special reason to do so. If someone can make progress on lower volume, then that should be exhausted before moving to higher volume work. I'd probably have her pull less and make smaller jumps. Is she doing power cleans?
