I hear ya TQ.
Sometimes with so much info available to us, it can get confusing.
All training causes some degree of stress and thus some increase in cortisol levels.
My take on it is if you look at a competitive bodybuilder in prep mode for a show, who is on a low carb diet (50% or less of his normal daily carb intake),
it is more than likely the low carbs that may make the athlete
feel like he is overtraining. Especially if he is doing 2-a-days plus too much cardio.
As an example, if someone is training, let's sat chest, 3 times a week, and doing 25+ sets, with a rep range of 12-25, supersets, drops, etc, and is doing so in attempts to burning body fat, for weeks on end, he will most likely not be
happy with his body fat levels because that type of approach will indeed keep his cortisol levels elevated. High cortisol levels = high(er) BF%.
If that same individual trained chest 3 times a week, say 8-10 working sets,
same reps or better yet different rep patterns with different loads each workout, then that athlete would more than likely be able to eat more carbs and avoid the extra cortisol levels and be leaner than the other way.
The first guy, depending on his threshold, has a far greater chance of walking the fine line of "overtraining".
The second guy, should feel and look much better and not be "overtraining".
But either guy, in a setting where the goal is to slowly get lean and stay lean,
should never feel he is in "suffer" mode.
If he does feel like this, there is probably other factor(s) at play.
And the other element is his level of enhancement, GH use or just HRT doses.
If he is hitting things hard, overtraining is almost impossible.

doent your body adapt to your training stress,i ask because you here that high volume,low carb,high reps,train more then 45-60 min, raise cortisol then others say overtraining is bs and as long as your nutrition is good you be fine
