Squat University on Instagram: "These exercise are great for building strong quads - but what some confuse is that stronger quads = bulletproof knees. Knee health is not about the strength of your quads but the quality of your movement & the way in which the knee is loaded (influenced by the action of the ankles & hips). . Shout out @izzyvergaraa for the opening stitched video & @muscleandmotion for the amazing anatomy graphics."
