for me I like to go higher intensity and this is something I kind of was looking forward to talking to you about because it has to do with how do you measure like so there's the there's the Mac the estimated heart rate which is what I do I've estimated and again all sorts of problems with that based on your physical meaning as estimating your maximum heart rate to take a percent event okay right yeah right I mean so so basically you know like if the more fit you are like you could be doing a more vigorous intensity exercise but your heart rate like doesn't go as high as someone who's not fit right um and then people that are older so there's of course I would say problems with that but um generally speaking that's one way but I'm also very interested in lactate and I know you are as well
