The squat is the foundation of human movement. Whether you are an elite powerlifter aiming for a world record, a CrossFit athlete racing against the clock, or a fitness enthusiast looking to move without pain, the squat is the ultimate test of full-body strength and mobility.

Most squat tutorials tell you what to do (e.g., "keep your chest up"). Dr. Horschig tells you why you can’t keep your chest up (e.g., "limited ankle dorsiflexion or a weak lower trapezius") and how to fix it.

In the world of strength training, few movements command as much respect—or deliver as many results—as the squat. Whether you are a raw powerlifter chasing a 600-pound pull, a bodybuilder sculpting tree-trunk quads, or a fitness enthusiast trying to fix chronic lower back pain, the squat is non-negotiable.
