Taking a hacksaw to our bones isn’t a realistic option, but, luckily, there is something we can do anyways: stand wider. Yup, that’s it. All it takes to artificially shorten your thigh segment, for the purposes of the squat, is to take a wider stance and make sure you keep your knees pushed out.
Obviously standing wider doesn’t actually shorten your leg. All it does is put your legs at a more diagonal angle which shortens the horizontal distance between the hips and the knee. The leg length remains the same.
