In today's episode we take a look at the literature to try and answer the question, "are deep squats bad for the knees?" We go over:
- Does squatting (strength training) slow the rate of arthritis progression?
- Are 1/4 squats or 1/2 squats safer then deep squats?
- What's the best dosage of squatting?
- Does everyone need to squat deep?
- Who should and shouldn't squat deep?
