In this way she can reach exhaustion at the end of the workout. Offer, at the beginning of a workout, an optional interval to be done on the condition that the crew feels that it can manage it. This enables the crew to bring itself to exhaustion if the workout the coach planned hasn't. The coach should avoid taking the crew to the point that it has to give up. It is pointless for a crew to row with no spirit or strength.
Progress is made when the crew is tired, but can still apply nearly as much power as when fresh.
The psychological effect of giving up is that morale, self-esteem, and pride are destroyed. If I were consulting with a coach, I would not make the recommendation that a coach help athletes develop a higher threshold of pain, and gain self-esteem. But if the coach set these goals for the crew, I could help her in developing the communication skills to further these goals. You notice that Wilson never mentions talking to the athletes about winning or giving them inspirational speeches. I don't know why he neglects these areas, but I know why I do.
