Incorporating an efficient and effective knee drive is all about motor control and mental dexterity. Unlike learning to land on your midfoot, incorporating your knee drive can happen more quickly. Since you’ll be firing your knee during the swing phase, you lose the high impact associated with Phase I. Driving the knee often lacks the soreness that you likely experienced when landing on your midfoot. Although most runners will instantly begin to increase their speed when practicing their knee drive, almost all agree that it feels unsustainable. It’s not uncommon to see a rise in heart rate, too. With repetition comes sustainability and efficiency. This training gives you tools to focus and make the knee drive a natural movement.
