This "homonculus" is a graphical representation of man's motor cortex. Notice how much relative "real estate" is dedicated to the hand. Also notice the proximity of the HAND to the LEG. There is spread of cortical neuronal activity to the leg fibers, so called "facilitation, when one voluntarily contracts the hand. SQUEEZING the bar during a SQUAT will dramatically improve your squat. Same goes for a DEADLIFT. Hand-leg connection. Your hands should HURT after every workout. This is an indication that you've trained your BRAIN effectively. Your muscles are just an offshoot of your nervous system, right? (Oh, don't stand behind the "glove" theory. The MUSCLES of your hands should hurt. End of story.) #GetSerious #Deadlifts #gripitandripit #DrBrettOsborn
