Yes explosiveness needs to be in there but you need to not forget Distance runners gain economy from actually running and too much explosiveness will lead to injury as we have seen in so many. Short-hills are the safest most effective to induce strength and coordination.Training is not just what you do but what you don't do. Speed and strength are related and to have better biomechanical support you need to strengthen not just the fibers but to strengthen them at max. intensity. There is no one way but many and more cost effective. Do you want to spend a few hours or 20min. Training is everything that affects the mind and the body. LSU?
How long should these hill reps last?
