Build to end

What is top end? There are several terms in use that describe pretty much the same thing. The key is rapid movement at high intensity. Think kicking a soccer ball on goal, or a volleyball player spiking the ball. Now extend that effort for thirty seconds to three minutes. For cyclists the best model is a sprint finish. I follow Joe Friel’s terminology and call this aerobic capacity work, since the goal of this exercise is to maximize the body's ability to process oxygen.
