Even strong people get sore if they try a new workout, because their body hasn’t adapted to it yet.
Scientific Claim
Trained individuals experience heightened muscle damage and swelling responses when exposed to novel training stimuli, despite prior training experience.
Original Statement
“The trained individuals in these studies are still unaccustomed to the one workout they execute. Many trained individuals can attest to the fact that if they perform a new exercise or train with a different set of variables, they get more sore than usual.”

Unknown Title
Even super-fit athletes got seriously sore and damaged after running for 24 hours straight—something they hadn’t trained for—proving that new, extreme workouts can hurt even the most trained people.
Contradicting (2)
Reduced muscle lengthening during eccentric contractions as a mechanism underpinning the repeated-bout effect.
After doing a tough arm workout once, the second time was easier and caused less soreness and damage — your muscles learn and protect themselves.
Acute muscle damage as a metabolic response to rapid weight loss in wrestlers
The study found that losing weight quickly made wrestlers' muscles more damaged, but it didn't test whether trying a new kind of workout caused more damage — so it doesn't support the claim.
