Strength training causes brain fog, fatigue

Hello,

For the past several years, my body has responded very strangely to
strength training. I can do cardio just fine - exercise bike,
elliptical, etc., but as soon as I do any kind of strength training -
even if it's just situps or pushups - my body responds in a very
strange way. For about 12 hours after my workout I experience
very intense brain fog, where I just can't think clearly. I also
feel
fatigued during the 12 hours after, but it feels different from
"normal" fatigue. It's hard to describe exactly, but my body just
feels "yucky", not that good tired feeling that you would expect. The
thing is, it happens even if I do a pathetically small amount of
strength training, like a set of situps for example. It even affects
me when I try to do the rowing machine on the lowest level for a
couple of minutes.


I have a theory that the problem might be something like "adrenal
exhaustion", which I've read about but doesn't seem to be recognized
universally. The reason is that my problems started after a very
intense period of strength training about 4 years ago. I worked out
4-5 times a week and pretty much shredded my body. At first I was
fine, but pretty soon I wasn't sleeping well and I had terrible brain
fog as well as fatigue. Anyways, I realized I was overtraining and
stopped. The problem is that I now seem to get similar symptoms as I
got back then, but even if I just do a pathetically small amount of
strength training. It's as if I damaged my body somehow and have
permanently lost my ability to recover from strength training.

Thanks very much in advance for any advice.
Scott
