I do sets of five all the time, but some days it's more sets of 5 than others. The more sets of 5, the lighter the weight. It's nice to have a day when the weight isn't so darn heavy and it's nice to have a day when I don't have to kill myself with so much volume. And it keeps my mind off all the stress of thinking every single freaking time I go in there I have to lift more than last time.
Female, 5'3", 49, Starting weight: 163lbs. Current weight: 135 (more or less).
I can squat 180lbs, press 72.5lbs and deadlift 185lbs
