Exactly what can go wrong with strength training
This is a list of specific examples of how strengthening can go significantly wrong without exercising extra caution, which is sadly rare in practice.
Misdiagnosis is a large category of ways that strength training can go wrong. Some problems that appear to be “simple” musculoskeletal problems, like back pain, actually have medical causes, some of them ominous, such as pain caused by a tumour, or a drug side effect. The failure to diagnose such things correctly can lead to prescriptions of completely ineffective or harmful strength training. Here’s just a few key examples, and there are probably dozens more (because there are so many surprising ways to hurt:
Chronic fatigue syndrome (unexplained fatigue, also often overlapping with chronic pain, which is why I’m including it here): these patients may seem like ideal candidates for exercise therapy, but if the cause of the fatigue is myalgic encephalomyelitis — a nasty infectious neurological disease that routinely evades diagnosis — exercising can backfire severely,24 and might even make the condition permanently worse.25

These waters have been muddied by the infamous “PACE” trial, a big British experiment which concluded that graded exercise therapy was helpful for myalgic encephalomyelitis patients. But the PACE trial has been tainted by scandal and harshly criticized as “uninterpretable.” There are good reasons to believe that PACE got it disastrously wrong, and exercise actually hurts ME patients: see Shepherd.

“We hypothesize that these crashes, or episodes of heightened fatigue, may have a cumulative effect on a patient’s health, and may compromise the patient’s potential for a full recovery.” From: Instructions for Stanford Chronic Fatigue Syndrome Patients.
