A brisk pace is considered one at which it is difficult to walk and have a conversation at the same time without halting sentences. For instance, "I met Marci for lunch...breathe, breathe...yesterday, and she...breathe, breathe...looks great." This means that as your conditioning improves, what is considered brisk will also change. https://ift.tt/1VMjaZw
