I’ve tried exercising occasionally, but have negative responses when I do. It’s not the out-of-shape “I don’t wanna do this” response because I love the feeling of pushing my body towards its limits, but instead I feel emotionally/physically drained afterwards for the rest of the day if not longer. I tried 20 minutes of HIIT on an exercise bike a couple of months ago and was absolutely drained for the rest of the day in not a good way. I had to sit in a chair and basically stare at a wall for an hour before the worst passed–completely brain-fogged and completely exhausted.
I believe it’s due to the paradoxical decline of ACTH (Adrenocorticotropic hormone) after exercise. Normal, healthy people see a rise in this hormone after exercise. Mercury toxic, adrenal insufficient people see the opposite, with a decline in ACTH. Andy Cutler (mercury expert) describes this situation in his book Amalgam Illness. I’m optimistic that after enough chelating I’ll be able to lift weights again without this happening.
Because of my experience I do believe that some people’s health situation dictates that they are better off with no exercise, but that’s an individual situation and people have to figure out for themselves what they can get away with or benefit from.
I haven’t lifted for roughly a year and a half now, but thinking back now I can’t wait to do it again. Squatting will be the first thing I do.
