Are Squats Bad for Your Knees? The Warning’s Best-Known Source Is a 1961 Study of 128 Weightlifters. Squatters’ Knees Have Mostly Tested Fine Since. Hours of Squatting at Work Have Not.

The deep-squat warning is usually traced to a 1961 study of 128 weightlifters. Trials since found squatters' knees no looser, and among 2,607 adults those who had strength trained had less knee arthritis; one trial pointed the other way. Hours of kneeling or squatting at work are a different matter. Most of the nine benefits of twenty squats a day rest on studies of something else.
