Well , I'm going to disagree.
If you are doing low rep ranges , how many people are going to do that type of exercise on a caloric deficit? It makes no sense to do that type work on low calories. if this is the case why would anyone do a high rep scheme being 1000 calories above maintenance?
You can absolutely tone muscle with circuit training type exercise, but the idea can be expanded to any higher rep low rest workout scheme --- diet permitting
