One of the keys to good leg action is what you do with your arms. Your foot will almost always land under your hand, so if overreaching with hand in front your leg will overstride. Just observe folks when they are jogging. When the hand stays close to center so does the foot. Thus move your hand nip to hip. You will develop a smooth and bouncy rhythm this way and engage the glutes to get the foot down close to under your body.
