Winners of most sports games tend to be decided by the small duels that repeat tirelessly throughout the game. Whether it is the face-off in basketball, a volleyball player blocking a spike, or a heading duel in soccer, jumping performance often is a deciding factor in who come out on top.

We all have good days and bad days. We’re never at our best all the time. As an athlete, you probably know better than most how much this is true. When you’re having a good day, you know it and you feel like there’s no limit to what you might be able to accomplish and when you have a bad day…. Well, that can be hard to talk about.
