Zheng Qinwen's comment on Gabriel Echevarria, her new fitness coach: "He understands exactly what a tennis player needs. The training he provides is precisely what my body requires and has been lacking. There are many methods for physical training, but the key lies in choosing the right ones and managing the workload, which is the most challenging part. Anyone can do flashy exercises, but every movement he incorporates into my training is exactly what I need. "
