The coaches at the Chicago Parisi Speed School understand the biomechanics of speed. Hip extension is a critical part of speed development and reinforces the mechanics needed to maximize speed development. Our coaches insert a wide variety of exercises into our classes. Every movement we include has a strategic purpose.
Sprint speed comes from primarily three joint actions: ankle extension, hip flexion, and hip extension.
Sled pushes are very popular in the fitness and performance training world. Their value is in achieving hip extension. While this is not easy, athletes need to focus on fully extending each stride. Sled pushes are also amazing for building work capacity. But do not get so focused on pushing, make sure your athletes are dragging. Both energies are key - pull and push work hand in hand.
