Performing squats with a full range of motion, specifically going below parallel, stimulates the release and benefit of myokines.
"Go below parallel on your squats if you can do that. Full range of motion. That's where that myokine benefit comes in." (said at 1:12:00)
No published record matching the claim that performing squats with a full range of motion or going below parallel specifically stimulates the release or benefit of myokines was located; this does not prove the claim false.
