yeah it does make sense from from that aspect as well since we're talking about vigorous intensity and adding more of a a stressor and a more stronger stimulus maybe you can recap some of what Dr LaVine Dr kabala talked about on the podcast when they were sort of defining the various training zones what these zones are because there is a lot of out there on that which is can be quite confusing to people it can be and some people will like to use zones for training I think it's common in sort of the exercise with you know coaches who are coaching endurance athletes to use this five zone model if people you know are familiar with listening to podcasts on Fitness they'll probably hear people reference five zones there are obviously other zones to use but yeah drvine defined these sort of five Training zones and kind of before I go and Define what these are and how people can use them to guide their training I think it's he kind of defined them using three different metrics and that we're going to use to define each of the zones but lactate levels are one way to do it but we're not really going to discuss that because in reality you know most people are not going to be measuring their lactate levels weekly monthly or even you know certainly not daily um during exercise and so it's kind of a moot point to say you know Zone 2 exercise is this lactate level most people don't really know what that is and so there are other ways to measure intensities and use these zones one way is just raing have perceived exertion or RP um and this is just a subjective measure of how hard you think you're exercising and uh this is typically on a 6 to 20 scale
