The vertical jump. The king of the combines that can make or break athletes contracts. Everyone is in awe of the height of the vertical jump. I remember as a kid, we would compete to see who could touch the highest up on the basketball net and then eventually the backboard. We jump so much that our bodies have figured out how to get the highest jump for ourselves. We want to be the king of the playground, or in my case, not the worst on the playground, so we developed this strategy about how to jump the highest.
