An athlete with no shortcomings would be a great challenge for his or her coach.
Ordinary physical exercise would keep a person healthy, but professional sports training was a more targeted enhancement to a person's specific physical condition. For example, a man who was weak might need a strength enhancement routine, while another one who was slow might need a speed regimen. In other words, strong purposes guide professional sports training.
But the training for an athlete without shortcomings would lack direction or purpose, which would pose a great challenge for the coach.
An athlete like Anshan Wang had reached perfection in every aspect. What was the most important for him, and thus his coach's task, was to maintain his current state.
Sports training was like sailing against the current. Improper training would lead to a decline of the athlete's performance, which would be especially obvious for high-level athletes.
