Personally, I can subjectively feel a difference if I can get in as little as one 60 minute session per week of low intensity sustained cardio (NordicTrack ski machine). That's nothing for an endurance athlete, but it has a noticeable effect for me. I remember in Lance Armstrong's book where he mentions really feeling incapacitated by his cancer or chemo treatment because a one hour ride was exhausting and normally if he only had time for a one hour ride he wouldn't even bother. To him, there was no real difference between training for an hour and not training at all. But to me, that one hour (even once a week) has a lot of value.Now, the follow up of course is what should we do when we only have two hours a week to spend on aerobic capacity. Still the same 9:1 ratio of the serious endurance folk? Or at what point does it change?
I feel like my KB ballistics are fine for non-specific "conditioning," but there's a dimension missing that the sustained low intensity stuff provides, even in relatively small doses.
