um yeah because again I'm going to argue that the older we get any time we have interruptions in training the cost of regain is so high so how do you factor that into a strategy around training for this person okay injuries exercise induced injuries happen in a couple of ways um it's very very rare that it's muscle that's the problem okay the only problem that you have with the cardiopulmonary system or cardiovascular system is systemic fatigue that's not really its fault right systemic fatigue so if you're not overdoing it globally and this would be your run down this is maybe you're getting sick really often any number of hormone Cascades or out ofac cortisol testosterone estrogen all off like things like that mood can't sleep appetite like that is those are some of the markers we look for of global fatigue so if that's not what we're talking about here you're talking about I got hurt through my back out knee hurts yeah neck is this knee is that back is that right what you're talking about is joint all right so the only reason joints really get hurt is repetition over bad movement patterns
