As a coach, I used to love preseason practice. (As a player I could have done without it.) I loved working with the players and coaches, the camaraderie of being part of a team, and the anticipation of opening night. Preseason was always electrifying.

Then came the first game. The scoreboard was turned on, and a new element was added—the element of stress.

As coaches, what do we expect from our athletes if we want to improve their performance? If they are going to be champions in the weight room, we expect them to be torn down. We expect them to push beyond their boundaries. When they do that, their bodies rebuild stronger than before. How do our athletes get faster? We put them on a treadmill, increase the incline, and again push them beyond their boundaries, beyond their comfort zones. Again, when their bodies recover, they are faster. Sometimes the increase is small but they are faster.
