Squats make knees stronger. Squats make athletes better. Squats are good for kids, teenagers, adults, elderly people, and anybody else who can perform them correctly. Squats are a functional expression of human skeletal and muscular anatomy, and the human body is designed to do them. The squat is the way that tens of thousands of years of evolution has adapted the bipedal human body to lower itself to the ground. It is the position in which half the population of South Asia spends the afternoon. And when done weighted, it is the best exercise in existence for strength, power, coordination, joint integrity, bone density, confidence, discipline, intelligence, and charm.
Health and fitness comes in all shapes and sizes. Every single one of these athletes is a certified bad-ass.
